Leaf Spring Shims?
I saw these in the Mid Fifty catalog. They list a 2 degree & a 4 degree shim.
My questions:
What are they for, how do you know if you need them, and how do you determine whether you need the 2 or the 4?
Confused as always...

The shims are used to change the pinon angle of the rear end. They are used to increase or decrease the angle of the drive shaft between the trans and the rear end. As to witch one to use depends on your set up. I'm sure there are many other people can help you more than this but it is a start. Ritchie.

The shims are placed between the spring and the axle to adjust the angle that the axle sets. As stated above this will allow the rear axel pinion axle to be adjusted or the front axle castor to be adjusted.

The castor information is in the Shop Manual

If you are using a dropped front axle or reversed eye front springs you probably need them. They are installed so the top of the axle tips back. More caster will make the steering center easier so the truck will wander less.
