Call the salvage yard- they can answer this for you, or, you could measure the width of both axles, and see if the companion flanges, and lug bolt patterns are the same.
There really is none. No factory f-bodys came with 4-11 rears in the third or fourth gena nd they are the only rears that will bolt in. There are plenty of aftermarket companies that can help out but nothig from the factory or a salvage yard. The rear suspensionwith the tourqe arm and panhard bar was unique to those body style and they were never offered with that gearset. If the car has a posi now just look into swapping the ring and pinion for a new set. Things like that are better bought new.
AnswerNone come factory with 4.11....that's an aftermarket gear. A Firebird axle setup should fit. AnswerCall a salvage yard, they will be able to help you. The axle housing design didn't really change that much from '70 to about '90 for the Camaro/Firebird/Nova/Chevelle- but there was a time when metrics was applied to them, and that is where I can't tell you.Answer
the mid 80's S10 will work with some minor work. you have to get the id numbers for the tags but most of the posi rears were easy to spot, they had aluminum drums.
take all the bolts out of the rearend pumpkin cover and you will see the rearend gears, push the axle inwards and you will see a C clip that holds it in place inside the rearend, pull the C clip out and then you can pull the axle out.
Yes but the gears have to be changed
Reverse and forward gears
3.31 or a 3.55 are good all around gears.
the backing plate on the rearend has to come off and there are C -clips that you have to pull out of each axle where they mesh with the gears inside the rearend and then you can pull the axles out.
it depends on how much the car wieghs and what rearend gears are in it and what rmp u shift gears in it
3.23's
Not knowing your tire size I would say you have 3:73 gears
3.42 should be stock.
I believe they are 3.42.
It depends on your rearend gears and transmission type. I have a 364CI with 410 gears and a 4 speed auto and depending on my use I get 8 to 14 MPG.
2.73 gears
