Okay Jim, what do we have here? Can you id it? 7/16 bolts, I don’t yet have the axle spline count. Suspecting a B-body unit. Any way to tell what series for gear ratios?
Thanks,
Kurt
12 bolt carrier............for what?
Re: 12 bolt carrier............for what?
need the casting number for the sereis or measurement from the table to the machined ring gear flange will be in the 1" -2" range (IE 1 7/16")
Looks to be from a 12 bolt pontiac (or what they call a GM Corporate 12 bolt Full size car 1978-1984 will have 28 spline c-clip axles and a ring gear diameter of 8.75
1971-1977 were 31 and later versions were 28 some c-clip some bolt in axle ring gear diameter was 8.875
ALL used left hand thread 7/16" bolts
SOME very few 1973-1977 Monte carlo, El camino and Cutlass were optioned with these rear if you have the BIG motors. 11" drums too.
