Order steel shims.
The alloy(zinc)'pounds' out over time.
You will need longer spring center bolts also.
You can often find the steel shims where heavy duty(semi's)trucks are serviced/repaired.
What was your caster set at?

Or cut and rotate the perches and get rid of the shims completely.

Kinda hard to cut the passenger side perch on a front axle.

Originally the caster was 2.6 degrees. I checked the Toe-in tonight and it was 1/2" inch. Waiting on Shims to increase the caster to 7 degrees. Will bring the toe-in down to 1/8 to 1/4 when I do the new shims.

Its not cast into the center section. The spring perch is welded on.

Beat it to fit, paint it to match!

A few swipes with a cutoff Wheel, a few whacks with a BFH, and they pop right off. Its surprising how little weld there is holding them on.

Yes the large end of the shim is to the front. I just ordered another shim that should increase it to 7 degrees. I will report back when I get the shims in (should get them next Tuesday).
You just contradicted yourself here.
Are you sure you know the correct way to measure toe-in??

Apparently it's been too long since I messed with a Dana 30. I know that they are part of the casting on Dana 44s and Dana 60s which is all that I have worked with the last few years. I will shut up now about D30s!

Yes, I know how to check the Toe-in. I have taken the leaf springs loose a couple of times adding and removing the shims. Also I looked at the Goodyear print out closer and they set the Toe-in at 1degree not .125". I should get my 4 degree shims by Tuesday. I will report back once I get them installed.

What kind of lift do you have. I put a 4" lift on mine and cant tell any difference in how it drives. It had a 2.5" on it before. I would think if you stayed with a cj spring lifted or not the caster should be close to spec.

I have never heard of TE given in degrees. Only fraction of an inch or decimal equivalent
Only camber and caster are shown in degrees.

Many 4" lifts don't use the oem shackles. Taller shackles change the caster.

The few alignment machines I've used have all given toe as an angle in degrees. They actually gave all of them in degrees - camber, caster, and toe, along with thrust angle and all the others... They have all been Hunter brand machines.
