Any recommendations on upper control arm bushings as far as brand or should I use rubber style like oem or polyurethane. Also any recommendations on upper ball joint brand. Thanks
If you’re using the stock upper control arms I would use Moog K7103 offset UCA bushings. If you install them for maximum caster (not what the directions show) you can get some additional positive caster which is very helpful if you’re running radial tires.
Unfortunately Moog is the only one I know of making them, their quality has gone downhill and I avoid them otherwise. But with standard UCA bushings and the stock UCA’s you can’t get much positive caster, which can make the car feel a little squirrelly with radial tires.
For standard ball joints a company called Proforged is making decent stuff, way better than Moog anyway. Not sure if you have large or small upper ball joints though.
Those are all large ball joints.....I like shopping Ebay for old stock Moog, TRW, etc. Good quality before lowering standards by going global. The price can often be pretty good, too.
Here are a pair of old stock Moog upper ball joints for 1972 and earlier. Also some later drum brake cars. These have the narrower stud. Be sure of your application. Decently priced.

Edit - just saw your post. You'll want to look for the K772.
Here you go. Even less expensive.

Maybe i've been lucky but i've always just installed stock pieces and have never had a problem.I think it's necessary to have components that are in nice original condition rather than beat up rusty parts.
