Does anyone know for sure if a 71-76 Impala rear will physically bolt into a 71-76 Delta 88? I am interested in putting a 4L80E into my car along with a lower gearset. As I am sure you know there is very little available for the big olds rear, whereas you can get anything you need for one out of an Impala.
Thanks

hi, i believe it should work, all the 71-76 b body chassis the same

 

The front and rear suspensions are the same on all 1971-76 B-body cars (except the wagons, of course). Yes they interchange. Keep in mind that the Chevy axle is 8.876", the Olds is 9.3".

 

Thanks guys
