73-87 a arms on a 68?

[Byoung330]

I am just about ready to blast my frame and paint it and then start suspension work. I was wondering if 73-87 upper and lower a-arms would bolt on with no issues. I know the cross members can be swapped but I’m wondering specifically about a arms only. 3 reasons why... I am looking at buying a arms with moog ball joints already installed from rock auto and of course they don’t have 71-72, I want to be able to go to autozone and get parts for the brakes and bolting a new control arm is easier than removing and replacing ball joints! Lol. I am open to other options as well like a decent affordable set of tubular.
