Im going to be putting 3/4 ton running gear on my 77 K10 shortbed.. the rear upper shock mounts are different between 1/2 and 3/4 ton frames.. Ive seen some people run the shocks upside down, but I dont like this for obvious reasons.. The rear axle will be a 14bolt-FF. Is there a better way? A custom kit? Ideas? mike ps- been lurking a little bit, nice site.
