front suspension

I use poly bushings. No squeak, little more precise steering. Since most mail order places don't name names, I went to a MOOG supplier for the joints. The jounce and rebound bumpers are rubber.
If you're buying tools, be advised that the upper ball joint screws in on the A-body. Some repair manuals say they press in. The pre-73s use a smaller joint than the later cars (same as B-body). I had to use a super long cheater bar to get mine out. I don't recommend using a ratchet handle on the socket (yes, love those lifetime tool warranties).
