i have a 64' gmc with springs over leaves, i would like to swap to the c10 version rear suspension of 2 control arms/trackbar/coils but i would like to use airbags instead, my question is can i bolt the control arms onto my axle and the current crossmember on it? theres a bunch of holes on it, its the one right at the end of the cab (my beds currently off) i figured its alot cheaper then to put in a 3 or 4 link
you'll need the Chevy perches, and the panhard bar...the panard bar may be fun to mount since you have a Dana rear in your truck, right? might want to find a 64-69 truck to get the 12 bolt rearend out of, although it would probably have 3.73 gears in it. The middle crossmember that the trailing arms hang from should be on the truck already. you'll probably need the chevy crossmember that the springs mount to?

check out Friendship Auto Salvage, right down rte 70, last time i was in there they has several 64-66 chevy trucks in there couple in decent shape too.
