Your honest opinion

Just to clear things up:
The 8.75 ended A body production in 1972 but Truck production ended in 1974. I have never seen a 73 or 74 B bodywith an 8.75 except a station wagon. They may have been put in the Charger & Satellite but I have never seen one past 1972.
1965 B was one width, 66-67 was slightly wider. The 68-70 B body housing is the same. 71-72 is W I D E! Something like 63" drum to drum. A pre 1971 B body 8.75 fits many A body cars. I have a '68 Coronet axle in my 67 Dart, my brother in law has a '70 B axle in his 72 Duster.
