Just have bought a 1998 Snoway 7' plow. Going to mount on a 79 wagoneer. New from a dealer here in NC is $600 The mount that came with it is for a 94+ S-10 Chevy. Is there a website for the mounts used?
Being that application is a very limited one, I doubt snow way makes a frame kit for that truck. You may have to take the universal frame to plow portion of that sub frame, and then have a custom piece to attach that to the truck.
