And different shock plates and U bolts to get the rear mounted (don't forget the Explorer 8.8 rear needs one side narrowed to even things up under an A body), a new driveshaft made to hook things up; and then you'll need to do a front brake swap in order to have the same bolt pattern front and rear, and then a different master cylinder to accommodate the different brakes, and an adjustable proportioning valve to get the front and back to play nice together, different brake lines and hoses to hook up all the new parts... get ready for the snowball effect.
OP, the first thing you REALLY, REALLY need to do is decide if you're building this to be what YOU want and to make YOU happy, or if you're building it to flip. You keep bouncing between the two concepts. Two COMPLETELY different approaches, which will take you in two different directions- which will get you different advice and suggestions. You can't realistically do both without taking a bath on the whole thing in the end.
