I've got a '90 chevy silverado k1500 and the rear cab frame support brackets have rusted, then bushings punched right through. Its common, I see a truck like mine every week with the same problem yet I can't find parts. Anyone out there know of an aftermarket repair kit I can weld in rather than fabricating it? Since it is so common I would think they do but I can't find any. The dealer only has the entire frame rail. Would be nice if a company out there could make replacement bracket to frame like the older mid 80's trucks I found those all over the place as they bolt on. Glen
