1965 Valiant rearend options

I haven't seen a 9" in a maverick. They came with the 8". I have 1 in the garage right now that I plan on putting in my 63 Valiant convertible. Gearing is unknown, but since it has a drop out center, I can have a few around to play with. You can get lockers, spools and limited slips for them as well as aftermarket axles. Since tire size is limited, I wouldn't think you would have to do much to make them survive.
