IDK if that will work or not.

Any B-Body from 1978 to 1990 will work, Caprice, Impala, Delta 88, LaSabre, and Parsinte.

If you get a different gear the speedo will have to be reset

1973 to 1996 full size 10 bolt 8.5 will all bolt in to the 78 delta 88. If you have a 10 bolt 12 bolt gut rear...it still should bolt in. The pinion shaft lenght is still the same. If you have a 7.5 rear you must stick with that size because of the pinio n shaft length being shorter. or you will have to modify the drive shaft length. shorter for a 7.5 to a 8.5 and longer for a 8.5 to a 7.5 rear. Ok? Jim
