I've been reading alot about tubular control arms and the G mod, tall spindles and tall ball joints for these cars. What I'm looking for is more highway stability, so more caster is needed. Well, the aftermarket a arms do this, but I really don't want to spend that kind of money for this little problem. I don't need super high speed camber gain improvements (although I am looking into bumpsteer solutions), and I don't need the G mod. So what i was wondering is this. If i use my stock rebuilr upper arms, weld up the holes for the mounting bolts, and re drill them back about 1/4", that should accomplish what I'm looking for correct? From what i can see, this won't cause any interference issues with anything. I figure I can get about 2 degrees with shims and another 3-4 degrees moving the holes back slightly. Am i thinking correctly?

Try shimming your UCA to increase caster. What steering setup do you have that is causing bumpsteer?

The front suspension is all stock right now. This Nova is just like all my first gen F-bodies are/were. They all suffered from bumpsteer. It's not horrible, and it's liveable, but at the same time, I'd rather fix it if I can, but that'll come later.

Bump steer is when you're driving and hit a bump and it jerks the steering wheel one way or the other, especially noticeable in turns.
