Do you know what year the Ventura is? It will be a 8.2 or an 8.5 and I'm fairly certain they are a straight interchange. I don't think the Ventura saw the 7.5. As for gear and posi, it could be posi and most of these cars had tall gears, 308 or taller, depending on the tranny and engine combo.

I pretty sure they do, the 72 Ventura should have a 8.5. Measure leafs on both cars and backing plate to backing plate to be 100%. From what I know, all Novas from 68 up, rear ends interchange.

I sold a 75 8.5 posi rear to a guy that wanted it for a 71, and the Ventura is the same under carriage as a Nova.

The 8.5 will work but be an inch wider on both sides in your car. Your wheels/tires will be 1 inch further out. The rubber or urethane bushings mounting on the top of the pumpkin are further apart also by 3/4 of an inch. I put an early 12 bold ( width same mounting dimensions in most 8.5's) in an 80 Cutlass. I adapted top arms with some work at the bushings to make it work. Offset kits ''offset upper arms" you can special purchase these days.
