Truck Dana

Alrighty guys, im getting a free Dana 60 from a family friend. It is out of a 87 or so Ram 2WD. I know that i'll need to tap holes for a snubber and add a Suregrip (posi) diff, what else do i need to do to make it

a) fit

and

b) Hold up to at least 700HP and 700ft/lbs of torque... not that my engine will be that ratical.

also for my dart
1) bolt in four link or back-halving?
2)Tub to the frame rails?
3) Can I remove the inner fenders?
4) Is it a good idea to "Swiss Cheese" my bumper brackets?
