Nope, Not even remotely close. Sorry.

65-70 B-Body Impala Caprice Biscayne rear will only fit 65-70 ONLY
1965-1972 A body rears all interchange Chevelle ,El Camino, Skylark, GTO, LeMans, Tempes,t Cutlass, F85 etc. ALL interchange.
1973 -1977 A-body all have to stay together also
Then there is the 1978 -1988 G-body they stay together also.

So those are your different chassis.
F-body 67-69 alone with Nova are all Leaf spring.

You need the 4 link control arm rears from 1965-1972 GM A body chassis. That is it.

Any reason you have to have a 12 bolt? If you are just hanging on the street and only a few track blasts a year IA properly build 10 bolt will do the job even under big block power. TOO much track and even a stock 12 bolt Chevy rear will blow a spider gear. Spider gears are the weak link in ALL differentials ... The street can not hold big torque so the tire end up just spinning which does not make a binding force on the drive like like a stick track and stick tires etc.

Just some info for you to think about.
