Problems setting Caster on Rebuilt front end.

One thing you might wanna check. The tabs that the eccentric cams butt against to move the control are are supposed to be STRAIGHT. Over the years, they tend to become rounded which greatly reduces the amount of adjustment. By straightening them, you can restore some lost adjustment and actually make a big difference in some cases. I have also come in behind the tabs with small pieces of 1/4" plate and welded there for reinfoircement. Then it won't happen again.
