None that I know of, your truck is to narrow compared to late model trucks or cars. Your best choice is to up grade the frame you have. There are a lot of venders selling independent front suspensions and disk brakes. The rear axle will be easy to swap out, and motor mounts are easy to come by. There is nothing a newer frame has that can't be adapted to you old one. Its a major job adapting the front sheet metal and cab to a newer frames. Joe
