1993 First gen GS300 rear suspension parts

[Jeah5656]

Hey, I have a 93 gs300 and I’ve redone a bit of the suspension, new front control arms, front links, front hubs, new coilovers all around, and then it was feeling smoother after replacing some of the worn out stuff. Until a weird wobble feeling started happening, found out one of my rear bearings went out, and popped the knuckle out and in the process found out some of the rear ball joints are pretty bad, and after putting everything back together with the fresh bearing and all, the wobble is worse. I assume it’s because removing the ball joints to get the knuckle out probably “disrupted” them and thought no big deal, but I can’t find any replacements online. Can’t even find rear control arms. Anyone know what I can do for ball joints or control arms for this? Or if there is another Lexus/toyota that shares rear suspension with the first gen GS300s? I haven’t had luck finding any of these near by at all. Any help would be appreciated thank you!
