you can flip ball joints and use drop spindles to lay 20s. Loosing the sway bar wont do much if you use 4 valves up front. two for each side. You will also have to pie cut the upper controls to get rid of the ball joint binding
we layed mine on 20's using aim spindles and reanglinging the upper control arm, and when using the spindles u no longer flip the ball joints. if i were to start over i woulda z'd the frame instead of using spindles
