What Differential Do You Have in Your 1965 Barracuda?
No wonder why you got what ever they wanted to put in your car when it was built. I have never heard any logical explanation why there is no code differences between the 7 1/4 and 8 3/4 rears in 66. Here is a page from the "Ordering information" from Chrysler Corp. Now in 66 were all open rears 7 1/4 and all Sure Grips were 8 3/4? It doesn't say and you should have been able to get either rear axle with a SG or open.
