The four bolt upper ball joints look like first generation Camaro, as do the lower ball joints. Just for example, take a look at these:

Also something to point out, make sure that the Heim joints on the A-arms are centered so they don't rub when reassembled. When the jamb nut is tightened, they should be able to move without interference. One of yours on the top photo isn't centered and needs to be turned straight. Hope that makes sense!
