I bought them off the SO truck.
It's been about 5 years, but at the time I was surprised that they were not that expensive. Can't remember the price though.
Here is what I've got.
I bought the magnetic rails that the Snap On reps use in the trucks. I can pull the rail out if I want, and this way I can organize them how I like.
I have had a Quickcar liquid filled for quite some time now and is an awesome precise gauge.

By the way long time reader just taking in all the info. I soon will be able to post a garage build in the near future.
