Mike, for the arms, one of the things I've noticed a lot of for aftermarket making new arms is the use of the uni-ball for a ball joint. I would think you could fab a bracket to bolt to the upper strut location of the knuckle, then have the uniball setup for it. For a shock setup, most manu's for desert racing use a coil-over setup due to the space configuration along with a 'Y' upper arm. The spread of the frame mount for the upper arm is smaller than the spread for the lower arm. Hope this helps some.....
