100 horse shot of nos for 440?

"A" body 8 3/4
8 inch Ford, from early mustang/comet (and some others) V-8, with 5 on 4 1/2 bolt pattern axles
"A" body 8 1/4
These three do not require much in the way of mods.
Also Ford (I think explorer), does need to have one side of housing shortened, and use two of the short side axles. Most have disc brakes and limited slip diff.
