How to adjust caster

[Tiger Joe]

We did a frame off resto on our 79 C30 and since it’s back on the road we aren’t happy wit the steering. Everything on the front suspension is new.

I understand camber and toe, but gotta admit caster has me a bit confused.

To change camber, I add or remove shims to both control arm studs. To changec caster, add/remove to only one or remove from one add to other. Which one though? One article I found online said add to rear but to me if I add to the rear isn’t that pushing the ball joint forward more creating negative e caster?


Someone tell me if this is correct- to add positive caster, either add shims to front stud or remove shims from back stud.
