8 3/4 question

If it is an 8 3/4 it is not from an Aspen/Volare, and if it IS from an Aspen/Volare it is NOT an 8 3/4. The last year the 8 3/4 was produced was 1974, the F-Body was introduced in 1976.

Measure the flange-to-flange distance and post it. Somebody will be able to tell you what it is. Oh, and if it has factory large bolt pattern axles, it's not an A-Body 8 3/4.
