Another personal project. Planning on not doing any big projects for customers and getting some work done on this car and the COE.

Got this car from a good friend of my grandpas. The story I have been told on the car is this - the original owner parked the car in 64 with 34,000 original miles to go into the navy. While he was in the navy his nephews broke out all the windows. When he got out of the navy he just left the car at the family farm and bought a new car. The story of the car was known by many hot rodders but no one knew where exactly it was located. One day this old timer I got it from was visiting with one of his wife's friends and was talking cars and somehow this car came up and it was her cousins. So this guy got a hold of him and bought it in the late eighties. He put a late 60's Pontiac lemans with 67,000 miles frame and running gear under the car in 1990. Then on his 50th birthday in October of 1991 he started the chop. No significant work was done after this.

Picture of the car in October 1991.

Picture of the car last weekend (25 yrs later) when I picked it up

Pile of extra parts that he included with the car. At least enough factory trim for 6-10 cars. Also 52 Buick trim, kaiser and Pontiac front and rear over riders, desoto and merc bumpers. Two sets of inside window trim panels, merc and 65 t bird front and rear seats. 54 merc frenched headlights and taillights, And tons of other ****.

This was the stuff not inside the car. After this stuff was put away I pulled the car in and emptied it out and had nearly as much stuff again.

He also provided a 50 grille surround. This weekend I will be going to get more parts which include the front clip, rear glass, more bumpers the 53 desoto grille, another instrument panel, early 60 caddy seats front and rear and 56 Plymouth front fenders to lip the merc fenders. I also get to pick another grille out of his stash that I haven't decided yet.

Thanks to all for the interest in the project.

Tonight I pulled the driver side lower quarter panel off to straighten. All the bolts came out effortlessly which was not my expectation. This panel is by far the worst panel on the car with the exception of some of the stuff related to the chop. Figured I would straighten all the panels not related to the chop first. Once I get the rear window this weekend I will inspect the flow of the back window of the car to the roof and trunk areas before I finish up all the welding. It should be good considering the previous owner (Roger) was good friends with **** Dean who gave him all the templates and instructions how to mark it out. But I need to see for myself before it goes any further.

6cef1ff1165cd2fb56c5677f6d8e1fd1.jpg

Started straightening. Actual removed the bulk of the problems with a shrinking disc on the back side of the panel. Will do some fine tuning with a hammer and dolly tomorrow.

As for it running. Currently it does not. It has never been wired since the car was put on the frame. Last owner planned on running the low mile 350 Pontiac that is in it since he really liked the previous mercs he had that ran that motor. It's not an acceptable motor in any way to me. I talked Roger out of a complete 401 nailhead with turbo 400 trans he had sitting in his shop. He through in a box of new finned aluminum valve, valley and spark plug covers.

Nailhead in a Merc? Cool.

Obviously it BEGS for a flathead... although it wouldn't be much fun with 110 HP.. so it's gotta be something else rare and weird. Nailhead is a cool choice.

Hope to drive this one quite a bit so don't think a flathead would be a good choice. Besides I'll be putting a flathead in my COE.

The other motor I would of liked in the merc is a 312 y-block but I also want one of those in my 59 F100 whenever I get to that one. I have one located but haven't been able to close the deal on it yet.

Nailhead should fit this build good and make for a fun driver.

Oh man that looks cool.

One of my all time favorite cars. Very high on my list of must have cars. Would love to build one in the future.

Looking forward to watching the build!

Picked up more parts for the merc this weekend.
661c2157006e1f765dcd7239d8cca944.jpg
For grille options I have two and a half 51 mercs, a 49 merc, a 53 Desoto and a 54 Pontiac that has already be cut down and rechromed.

Bumper options, two 51 merc fronts, one 49 merc front, two 53 Desoto rears and one 51 merc rear. Was supposed to be a Desoto front but he can't find it.

Over riders a set of Kaisers, Pontiac rear, 49 and 51 merc rear. Maybe a 51 front. A box full of the 51 front and rear bumper guards.

7591ece9e4915bcb7822829a6b3ba329.jpg

Front clip looks very straight and solid.

Seat options: 65 t-bird and ~60 caddy front and rear and the rear for the merc. He has no idea where the front would of went.

Checked the flow with the back window sitting in and it looked good.

Forgot to pick up the 55/56 dodge or Plymouth front fenders for front wheel opening. Will have to grab next time I am up there.

Also picked up a TIG this weekend.

Proof it wasn't all play this weekend. Spent a little time straightening the rear quarter.

Then decided I am way past due on a bullseye pick. Haven't tried it out yet but it is a lot more rigid than any others I have used.

First weekend I've worked on the car in the last couple weeks. I installed a parallel lift that I bought at the first of the summer. Wasn't going to install until after I added on but I couldn't stand to work under cars anymore with this thing sitting out in the weeds. I have decided that I am very good at making my small shop even smaller.

Quickly ran the sander over a lot of the car to smooth it up and get a feel for how much work I have ahead of me. Pulled the passenger quarter and started straightening.

7e463fc0a2421e7937fa080fa0a6f263.jpg

Made a panel to replace the Swiss cheese section of the rear quarter. Would do differently if I was going to do again but I should be able to make it work.

75ec11781ebaf2c05b5c583a508aa72b.jpg

Lift with no car. Has two rolling air jacks in the center. When I add on I will move the lift into the addition and sink it flush into the floor.

Also made my kids Halloween costumes

Didn't they put triple deuces on the nail heads? Man that would be sweet in that Merc.



I know they had factory dual quad setups but not sure if they had six packs from the factory. I would like to come up with a cool induction setup for it.

Been doing metalwork every night this week. Growing up a body man I never got into this level of crazy metal smoothing. I cant decide if it is addicting or if just pisses me off how inefficient I am at it so I keep on going.

Nobody has said it yet so I'll be the first.......YOU ****!!!!! :thumbup::thumbup:

Nice purchase on the Merc. Looking forward to seeing the build of it. And another :thumbup::thumbup: on deciding on the Buick Nailhead. In my estimation, two of the best looking engines when they are dressed up is the Flathead ford, and the Buick Nailhead. And I like the idea that you are going out of the box by dropping the Nailhead into a Merc. Most would either choose a Ford engine, or drop in a SBC engine. I like to see when someone does something different than all the others.

I'm subscribed to see how things progress.

Straightened the passenger rocker, fender and hood this weekend. Starting on drivers side.

Still need to melt the lead out of the holes where the emblems were previously removed and weld up the holes.

Both sides of the car have straightened out pretty nice so I went to the disaster on the roof. I forgot to take a picture before I started but took one when I thought about it.

For some reason they used a pick hammer to beat the roof up on this side. Luckily the other side is much nicer (just have to deal with the welds).

5f94e69a63645979dfefef2d3dfc6948.jpg

No quite sure what all I am going to do to clean up the welds. I know I will be remaking the band across the bottom in two pieces instead of the many pieces seen in the photos.

My forearms figured it was time for a break from that so I started on frenching a headlight. Also have the other side ready to weld in.

3458786be84ad5f136157fb4a894a23f.jpg

Just noticed I didn't take a picture of the drivers rear quarter, I have the piece I made tacked in.

Picked up an Argon tank for the TIG on Friday and played around some. Realized I need to order some new electrodes and collets before I do any real welding on the car.

Played around with the nibbler today. Made a die weld fixture and a couple sets of dies and a few practice pieces. Will do some fine tuning and make new pieces for both sides.

Another quick practice panel tonight. Just eyeballed the radii and dimensions to see how it would work out. Need to smooth up the dies then make the real pieces. Having lots of fun and learning a lot while playing with the reciprocating hammer.

The real piece needs to be lengthened to remove the previous welds.

You're doing great work! It should be a nice car when it's done.

It should be good considering the previous owner (Roger) was good friends with **** Dean who gave him all the templates and instructions how to mark it out.

**** Dean was a proponent of swapping in the GM chassis under those Mercs, there were a bunch of articles about it in the car mags back in the 1990s. Apparently they fit very well with a minimum of cutting and adapting, and he could do the swap and have a running car in a day.

Thanks to all for your comments and following along. I haven't been able to get back in the shop the last couple of days so no real updates. Being a personal project I do try harder to learn new methods and don't just stick with what I know. I am having a good time and really like not feeling that I have any deadlines to meet.

Like Robert pointed out the Trumpf has sat idle far to long. It should start getting a lot of attention.

On the Dean articles for using Pontiac style frames, I wouldn't mind seeing them if anyone knows where they can be found. I have searched some with no luck. This body has already been mounted on the frame and it is very clean and surprising how well they fit. The couple things I would like to see are what has been done on the radiator support mounts and radiator. I don't think these will be too difficult but would be good to see what others have done.
