I have a '72 C10 that I would like to convert to a K20 with around 10 to 12 inches of lift. It seems like it would be real easy to use some box iron and bolt it in place of the leaf spring on a 10 bolt front and attach it with a spring bushing (like the one's from ORD) to a bracket welded to the frame somewhere under the cab, which would make the bars about 4 feet long. The truck is 2wd so it already has the right steering box for crossover. I was thinking of this idea because I want to use air bags or coil springs instead of leaf springs. The rear already has a coil spring set up. Crazy articulation and massive ground clearance isn't an issue as this truck will never see any rocks. It will be mostly street driven, used about 3 times a year in truck pulls, and mudded occasionaly. It also seems like this would eliminate any axle wrap. Thanks for any opinions.
