Question for those with live axle swap

I have found a wrecked 03 Mach 1 for my axle swap finally . I want to run a 10.5 wheel in the rear, so do I just take the factory quad shock off. Or is there something else I need to do? Other suspension, etc.? The wrecked Mach already had 10.5 inchers in the rear with no quads, and adjustable upper and lower control arms from HP motorsport.

Anybody?
