no they will not fit the gear ratio is different and the 4x4 axles are longer you will chew out the transfer case as soon as you put it into 4x4 on something packed
will a 1988 rear end fit under a 1965 chevy truck
No it wont as thePontiac's were 8.2 ring gears and so were the Chevy but the pinion shaft is a different diameter and the axles use pressed bearings and external retainers where as the Chevy used c clips to retain the axles.
depends if you are talking about the whole rear end or just the axles themselvs, and yes to both of them but if you take out 3/4 ton axles you will need 3/4 ton axles to put back in and so no. if you take the whole rear end of a 1/2 ton and put in a 3/4 ton rear end it should fit well
Hit a bone yard. They will have racks of them and know what can be made to fit you truck. Or you can have yours rebuilt at a shop.
