So I lost my mind and bought a 48 3/4 ton 5 window. Diamond in the rough. Did I mention that I have zero prior resto experience? Anyway, one of the discoveries I've made is that the rear and corner windows, while intact, had leaky gaskets. In turn, the flanges (?) that surround the rear windows (that the gaskets/seals attach to) have considerable rust damage - read, unusable. What to do? Patch panels do not seem to be available from the normal sources. Likewise with the innerliner (the sheetmetal spotwelded into the cab from about the rear of the doorframe aft and down to the cab waist). I'm in waaaay over my head here. Any advice appreciated.
