I believe Lang has a thread restorer kit containing 5/8-11 tap. I don't know if they sell individual pieces.

I rebuilt a pulling engine and saved a 5/8-11 head bolt to make a thread chaser out of. I stuck it end my mill and used a ball end mill to cut 3 slots in it by eyeballing. Works great to clean the threads out.

The 48 piece master set contains a 5/8-11 die but not a tap.

Cut some slits in a high grade bolt? Depends on how bad the threads are
I would do this. Take a grade 8 bolt and use a cut off wheel at a negative angle to cut 2-3 slits in the fastener

A Thread Forming / Rolling tap is ideal for sizes that the rethreading taps are not available in. Unlike a standard taps these do not cut threads and remove material but they form it into place and actually create stronger threads so they are perfect to use as thread chasers

Thanks for all the replies. I'm going to try the grade 8 bolt method first. I'm still learning a lot of this metal working stuff so if I mess it up, I'll still learn something. This is for a bunch of rusty nuts that came off a 1980's Toyota pickup my son is restoring. I am cleaning up the 5/8 nuts and bolts partly for the fun and partly for the practice with thread chasers.

Any threads on that Yota are definitely metric unless someone's tapped/die'd them different.

BTW, this is a great book for those pickups. Highly recommend saving your son a copy while someone still has it up.

How to Keep Your Toyota Pickup Alive: Step by Step Procedures for the Compleat Idiot for 1975-1987/2 & 4WD

If so inclined the physical books (used) can still be found but they can fetch a pretty penny.

Sorry, I should have elaborated. The bolts were for a wood bed that the previous owner made and put on to replace what the truck came with. My son bought the truck a few months ago and took the wood bed off as it was in terrible condition. He is in the process of fixing the truck up to use for camping and off roading.

Thanks for the link! I downloaded and saved it and just sent a copy to my son.
