70 c10 short bed step side replacing coils with bags... i dnt need brackets for the rear right?.. and on the front i have seen a flat sheet of metal on top of the lower control arms and i also seen a cup.. whats the diffrence? which is better?

Yes the rear should be a "bolt-on" install, depending on which bags you have, you will need to drill hole(s) in the frame for the upper mounting bolts and airline fitting, the bottom sits on the trailing arm and has a long bolt that goes up through the arm from the bottom.

The front uses the plates for the upper attachment (the plate spans the coil pocket and holds the bag) and needs the holes drilled around the perimeter of the crossmember. You also have to drill a hole for the airline to exit the crossmember (in the existing coil pocket basically) The cups go in the lower control arm coil spring pocket to retain the air bag. These are commonly trimmed down to provide more drop or are replaced by cupping the arm. This involves cutting out an 8" hole in the arm where the coil pocket is and welding in a piece of pipe with a bottom to bolt the bag to. You can find a lot of info/pics in the suspension forum as well.

ok thank alot that helped alot.. where you think i should get these parts, at suicidedoors?
ohh and also is the bottom cup welded to the arm?? i dont see how u would bolt it down?

No problem, thats what we're all here for, to help each other out. I would use a vendor off of the suspension forum, Suicide Doors, AVS or contact Way2Lo2.... they should all be able to hook you up.

The front lower cups are not attached to arm in any way, the cup rides in the coil pocket just like coil spring did, the air bag should keep the cup "locked" into the arm during normal operation.
