I'd suggest MOOG brand ball joints... I went through 3 sets before I got fronts that fit, and two on the rear. I got mine from Advanced Auto but lots of folks can get MOOG stuff. The MOOG ones were a perfect fit and were better quality IMO. What body kit type stuff are you looking for? Full kit, widebody, decklid and scoops? Options are rather limited right now in the way of kits, but we're trying to change that with some of our custom stuff. We work in all metal, but we have a few items we're going to be producing more of soon. You can see pictures of what we did with mine
HERE. Those are the parts we're planning to reproduce... just scroll down to the custom parts section and you'll see several pictures. I know they aren't everyone's cup o tea, but most folks really like them... especially when they see them in person.
