What is the difference between the 3 bolt ball joint and the 4 bolt ball joint (upper), other than the obvious. Were the 4 bolt bj's used in the big blocks or what? I have to replace the right side on my '68 due to an unnerving clunk that developed last weekend.

Just wondering. I gonna clean mine up today to see what kind I have.

4 versus 3 bolts

The 4 bolts are from 65ish to 69 early 70 maybe.3 bolters are for 70 and newer.The replacements were three bolts as well if a whole upper arm was replaced. Both are right Use what ever you have. Catz ya Ray
