9 Bolt questions
'85 T/A with the 7.75" 9 bolt rearend and I was wondering what my options are for gears and posi.
The only aftermarket gearset I can find are 3.70s. That's fine, kinda what I wanted anyway. My question is; Are there any aftermarket limited slips available for this differential? I don't think it has one now and if so it doesn't work at all.
I like doing burnouts and it sucks with only one tire frying. I was thinking of swapping in a 7.5" 10 bolt so that I would have a better selection of gears and stuff. My car is mostly stock so I'm not worried about breaking it. Good idea?

They should carry about any gear you want and they also have posi units and even carriers!
