1978 dodge aspen rear axel

first off do you know how many bolt cover your rear has and is it square or round.

If you can find one an 8 3/4 from a 66-70 B Body/ with the spring pearches/shock brackets will fit, does away with the rubber cussion mount. Had one in a 77 Volare years ago. Spring perches are of a bout 3/8" but will fit fine & it's bullet proof. I don't remember if I had to modify the driveshaft length

Chrysler Fifth Avenue through early eighties through '89 model year. Chrysler LeBaron '77-'81. Dodge Diplomat - This applies if it is not a former police /taxi car

and of course, Plymouth Volare sedan.

Dodge Diplomat cop cars have the same rear end as the stock, Aspen/ Volare station wagon rear end. Is your Aspen a station wagon? If it is a station wagon it probably doesn't have same rear end as the Chrysler Fifth Avenue Dodge Diplomat and 77-81 Lebaron sedan. See:

i got a rear end from a 89 chrysler fifth avenue .where could i purchase new u-bolts? old one's broke.
