Congratulations   nice work   

OTC should be a good tool.

I was reading some on the F body and Nova sites about troubles pressing in the Moog serrated lower ball joints so even without my second coat of tremclad on the LCAs I figured I would see if this was going to be an issue. The moog joint is 0.014" bigger than the stock Delco ball joint with the serrations, and no it is not an oversize joint...stock replacement. Got out the ball joint press and off we go! Same issue that was detailed on some other sites, these joints have a tendency to **** over and jam. Knocked that POS out before I did any real damage and off to the parts store.

I read on other sites that once you use the moog lowers you will always need to replace with moog lowers. The serrated joint will tear up and enlarge your nice LCA bore. I have a 50,000 mile car that had never had lowers replaced and they were still tight but one boot had a hole in it and I could not get grease into the other joint.

I ordered 2 AC Delco lowers today that are not serrated. If anyone is considering a coil spring replacement or ball joint replacement on a 73 to 77 a body or even an f body I would recommend Moog uppers due to the one piece casting and AC Delco lowers that you can press in without a 50 ton stand up press!

Bring on the opposing opinions....there seems to be a lack of info on coil spring and ball joint preference on here.

I put new sprigs & shocks & upper ball joints in my 73 when I took it all apart to paint it. I bought new upper control arms from pontiac at that time. Complete arms. I also got front & rear springs from Pontia, when I put them in & even now 10 yeras later they are still to high. I'm going to break down this year & cut the springs at least 1 coil out of them as they sit to high all the way around. I ordered all of the springs according to the chart in the parts book at that itme. I just read about 2 months ago that when ou order from Pontiac or GM that when you get new springs for your car, no matter what you order you get springs for a car with A/C no mater what you ordered because thats how they keep the older cars from sagging no matter what. For me the car sits way to high even now. I didn't drive the 73 for a few years while I was redoing the car but now that I'm driving it , it rides great as it always has but the amount between the tops of the tires & the bottom of the fender wheel is to much. It looks as though I'm driving a 4WD car. It's really not that bad but I think it's to high for me. I'll take the coils out & cut them. I have & used my coil spring compressor & mine came from Harbor freight to. They may look a litte spindley but they do work just fine. I have both kinds , the individule ones for coils & the single sissior type for macfersion strut & have had no problem with either one EVER. I do use them quite a bit to. So don't be afraid of the spring compressors from Harbor Freight, they work just fine.
