not without swapping the whole rear axle. its currently got the original single speed with the 6.17 gear set. I recently built an AD chevy for a fella and swap the rear axle and added the front disc brakes per your recomendations. that particular truck was repowered with a 350, nv4500, and a dana 70HD. Thanks for the help with that btw. I am just not ready to tackle that swap again so soon after the last one lol.
