When I bought the car back in 1988 the orginial rear end was supposed to be an extra part, which according to the car data tag was a 2.79:1 conventional open rear end. The car had had the rear end replaced with a 4:11:1. After all these years I am doing some major changes which include changing the rear end to something which will allow me to drive longer distances. I decided to take a look at the rear end which has been stored all these years. It is a C7AW-E. Is this a 67 3:50:1 Equa-Lock Differential which or course would not make it that which I thought it was?
thanking you in advance.

The C7AW-E is the case casting number, it is the standard single rib 9 inch case found in millions of cars and trucks from 1967 to 1985 or so. That number won't tell you much, since you have it out you should be able to count the gear teeth and identify if it is trac loc or equa loc visually. Look at my web page in signature for photo references.
