I went down to 4 Wheel Parts (barf) and bought some 6* shims. they have a slight curve to them like they are for an axle over. Do I use them or take them back?
I ordered a set of 6° shims and they came the same way. I called Skyjacker (who's shims they where) and asked them. Yup, it's for a spring under, grrrrr..... I had a friend mill the curve off.
