compressor,gauges,manifolds,hoses,BAGS, brackets,x`s dont need a bridge so dont worry about that {no cutting of the bed to reinforce the frame.} since you wont be laying frame or hitting 3 wheel motion/pause its not a factor. then all your lil "T","L" connectors and fittings
accumalators{if you want nice non bumpy ride} - would be best get 2. one serves each axle
a cheap kit f,b,s,s with all fairly cheap stuff about 800-900.
your best getting fast bags, blow jack hoses,independant switches and gauges ,also a 4 manifold set up .heh it never ends
