84-92ish Lincoln Mark VII & 82-end of rear drive production Continential also 61.5" wide w/ disc brakes, BUT 5x4.5" pattern.
94-98 Mustang 60.25" w/disc brakes and 5x4.5" pattern
99-04 Mustang 61-5/8" w/disc brakes and 5x4.5"
The explorer axles were plentiful here, but the 3.73 locker was hard to find.
2 out of the dozen or so explorers I found in one lot. The other one I did not get was toast.
Not sure about the ratios in the cars compared to the explorer.
You should pick your rims and then see what width you need to make it work.
The picture shows my rear setup with the explorer rear and newer mustang wheels. The tires would be all over the bed sides on this 50 model.
