I got my car aligned today and I am not at all happy with how it drives.
Here are my particulars: 67 Barracuda. Aspen spindles. Offset UCA bushings set for max positive caster. Everything in the front end is new rubber Moog bushings. Wheels are late model mustang, 245/45/R17 tires

The alignment guy, who was recommended to me by another Mopar guy, said he could not hit the numbers I wanted. Here is what he actually did:
Caster: +1.7 degrees left, +1.6 degrees right
Camber: +.2 degrees left, +.5 degrees right
Toe: 30 degrees total

He said he could not get the caster numbers even close.

The car wanders and is freaky on grooved/patched roads. It needs more caster, right? I've done this same set up on two other cars it was never a problem to hit 2.5-3.5 degrees caster. Is it possible that the manufacturing tolerances on this car are way off? What should I be looking at first?

I just verified that the bushings in the upper arm are correctly orientated. Do I need to make sure the strut rod bushings aren't too thick?
