What Differential Do You Have in Your 1965 Barracuda?

However, there was another at least one interchangeable 8.75" that predated both of those, I believe my Dad's 59 Chrysler wagon had one, and it was common, so did my 62 Dart.
Oddly I see no 2.76 offerings.

ANd I juste deleted my link tab. Yes, 8 3/4 rears started in the 50's. I was talking about the A and B body rears of the mid 60's.
