a couple of item, as you will see i am very new at this, i need to know which way the upper control arms go on my chevelle, there is a straight side and a curved side, which goes forward?, also i installed some new lower ball joint and they go further up in the spindle then i think they should, the key hole has a gap between the nut and the key hole, did i get the wrong ones? thanks for the help, i am learning everyday!!! steve

on mine the straight goes forward.

It looks to me like they are wrong,on my 64 there was no gap between the nut and key hole and if I remember right the ball joints are the same from 64 to 72. Both my uppers are one marked L and one R. Welcome to Team Chevelle.
