need some help from you bag guys

[pkj]

i have all 4 gags just about mounted, i have 2 compressors mounted, i have a old settling bottle i am setting up for a tank. how do i plumb this system for a simple set-up? i wat to be abel to controll the rear seperate from the front. system diagrams i see always show the front using 2 fill and 2 dump valves, why? i want to keep this as simple as i can but not getto. what are all the parts i need including drains, filters, check valves, tees, etc. next question i have is, i have some sets of ground force lowering shocks from our f-150projects. i am trying to see if these will work for me. they are left overs.
one set is oe10488 c331u1f
one set is 21301 c097z3
since they dont do anything with our trucks anymore they cant really tell me any thing. my truck is a 68 c-10 i am looking for 3-4 lower front maybe more, 5-6 rear. this is a mild drop for bags but its the route i chose to go. any help would be great. thanks, pkj
