Personally I think a 9" is overkill, they are harder to find because all
the drag racers and street rodders have grabbed most of them. The Ford
8" is a very good rear and can handle way more torque than your engine
can put out (it was used on many v8 cars) and are a lot cheaper. The
last 8" that I bought I paid $50 with the right gears and good brakes.
For highway cruising, the 2.79 rear that was common in Mustangs and
Falcons may be ideal. Some of them were also available in 3.0 to 1.
