duster alignment specs???

it really depends on your tires, wheels and intended usage to fine tune the alignment, but i agree that you need to take what the computer says for a 72 duster and thrown them in the trash!

I run a 17" wheel with a 225/45 tire on it - i do alot of highway . high speed driving, (not road course) but just normal driving - and for that reason i want to use the most of my tread, so a zero camber was selected, if you do road courses, and care less about tire wear, then negative camber is in your cards, same with say a 14: wheel and tall tire combo - there will be alot more tire flex so that helps compensate.
Caster I got lucky - I have stock arms and got 4.5 degrees positive caster - without offset bushings. the guy doing my alignments said thats rare for a mopar - but I dont have an excessive rake ( which will affect caster) and the car was never wrecked. Positive caster helps the tires go straight - kinda like a shopping cart's front wheels - you push it and the wheel automatically wants to go in that direction.

My toe ajdustment was zero'd out for a few reasons. 1 - I upgraded the tie rod ends and sleeves to the larger c body sized ends and used solid sleeves. this eliminates flex where most rear tie rod end equipped cars ( old mopars) car go toe out during hard braking. If you toe out in these situations it causes the car to want to steer, and wander - not something you want during a hard braking, panic stop senerio .
