Mopar 8 3/4 or Ford 9?

How bout keeping the Ford 9" and finding some Ford Explorer rear discs (bolt on)? Lots of them "clunkers" out there. 5x4.5 bolt pattern

Or just buying an 8 3/4 out of a tub and narrow it....5x4.5 bolt pattern.

I'm guessing either way you are gonna get new axles/ rebuilt center section etc....right??
