8 1/4?

Its got a 10 bolt cover-like my 8 1/4.

My 8 1/4 has been doing great, now it has a auburn limited slip but its not very tight and the right tire does chirp when shifting gears. But heck, I had a pro shop set it all up with new parts for $700+ bucks back in 1997. The first few years it was tighter but I just change the oil every few years-first year 2 times-and must have 50,000+ miles on it now. Changed oil last year and the teeth all look good. My ride is 3700 lbs. The gear is 3.91.

Motors a 318 and last year got 360 heads so it break 1 day but thats what I thought 5 years ago too.
