8 1/4 OR 8 3/4 A body rear axle

I am doing a small block 360 swap in my Valiant and I need a rear end with a little more strength than my 7 1/4. I'd really want a 8 3/4 but they're so expensive, I'll take a 8 1/4 no problem. Located in 43920 Ohio. Preferably with brakes on it, but if not there is no problem.
