The small bolt pattern A bodys require different uppers.Not 100 % sure on lowers but I believe they need them also.It oooks like a later a body kit.if it is they work good.i used tall spindles on my 65 and prefer them to the shorter
A body spindles.Rocky
Would need a different upper control arm or the Dr. Diff spacer unless the knuckle is sized for the smaller ball joint.
the lower arm is the same , the difference is the ball joint which has the same size stud for all a bodies and all brake sizes.
