Went to hamilton today to pick up this fine specimen.
It's a 8.8 ford diff out of a 91-99 explorer. There are a few reasons for using this. They are cheap ish, have discs and a decent handbrake setup , lsd, 31 spline axles, same diff as a mustang so plenty of aftermarket parts available, and if you narrow one axle tube 3" and use 2 short axles it makes it just the right width and pinion offset for a valiant.
I do have a 9" that I was going to use, but it has already been narrowed but not enough. New housing and axles was going to be 2k, plus rebuild the diff and get a lsd center, plus brake conversion, was probably the best part of 3.5- 4k.
And yay, wheels fit over the brakes.
