pivot ball stud won't budge
i'm replacing my clutch and have an adjustable pivot ball stud to install. The old ball stud will not budge. It's been soaking in pb blaster for days. I don't want to go too crazy with force. I have the 90 deg wrench with a foot long pipe and it will not move. Should I try heat? how careful must I be with the aluminum bell housing? Any ideas?

Heat the aluminum with a propane torch<dont worry it wont melt>
Once its good and warm take a candle(unlit) and melt some wax into the thread area. betcha it spins right out.
Aluminum has a faster cooling rate than the steel stud. Thus the bell housing will contract around the stud when it cools. The reason its stuck is because of the dissimilar metals. Try the wax trick it'll work

Wow really never heard of it?? It's an old school trick from times before the invent of penetrating lubes.
The parafin wax from the candle is a lubricant it flows really easily when heated and can get into the smallest pores and seams of the threads. It wont dry out and stays in place even after the part has cooled. Its a great trick when removing header or old exhaust manifold bolts.
Also it can be used when drilling through metal or tapping holes
