Raising Pit Frames

[eddieg]

Hi Fellow Mechanics, Years ago when I would raise the Pit Frame just a litte (from pin deck). I used to use a half cut metal shim from the automotive store, I cannot remember what the metal shim is called? I would use this metal shim instead of completely unsrcewing the pit frame and taking it off to put washers under it. This would save me time and do just the same job.
So my question is, what is that shim called? I need to go get a box!
Thanks for the help in advance.

I take a thick 1/2 in. washer and cut a slot in it.

Thanks PJ, but these were not expensive and I didnt have to worry about cutting them.

Eddieg:
Machinery shims are available at any bearing/belt store.

Those were alignment shims, used on the older upper A-frames to adjust castor & camber on the front end wheel alignment. They came in various thickness also depending on the amount of adjustment needed. Auto parts or alignment shop should be able to hook you up.
