7 1/4 Rear Differential ~ Experiences

'69 Coronet would have had an 8-3/4 in it.

The car has a B-Body 7 1/4 in it from the factory, it is a '69 Coronet Deluxe 4 door 318 column auto.
I still have the car for that matter.
I also have a '69 Coronet 440 4 door 318 column auto with a B-Body 8 1/4 rear end in it.
(The first year for the 8 1/4.)
