I want to get some studs but don't know the thread size. I should have bought the studs w/ my TA cover but didn't know they offered the studs at a reduced price (bought the cover off ebay) Since I'll order some stuff from Summit soon I figured I'd just order some generic ARP studs through them and use those.

 

It's been a while since I had a 9 bolt apart, but I think it has 3/8-16 threads. It might be 7/16-14. I don't have an old housing anymore to check.

 

def get them. im also unsure on the size. but i got them for my ford 8.8 when i rebuilt the posi with carbon fiber clutches and a moser support girdle. the ARP studs just look and feel stronger... also gives u alittle more insurance

 

no one knows for certain what the size is?

 

TA mentions this on their website

Australian 9 Bolt, 3/8” Dia x 2-1/2” Long

Sure enough I can't find a 2.5" stud w. the crappy summit catalog....if it's something out of the ordinary you get no pic and a shitty description...hurrah!
