Saggy Cab

Hey, I just bought a '91 Sierra and the cab corners and supports are rusted out, causing the rear of the cab to sag a few inches. I've heard that if it isn't fixed, it could cause the windsheild to crack. I've heard of cab corner kits to fix the visual holes but it doesn't do anything to support the cab. Right now the rear of the cab is sitting on the frame. I know most of you have either new trucks or live in a place without snow (therefore no salt to rust your truck) but if anyone has any info on this problem, it would be appreciated.

If the cab is rusted out to the point that the cab is sitting on the frame as in the cab mounts are no longer supporting it I kinda doubt you are gonna find anything prefab to fix that. Id take the interior out and find out exactly whats rusted through then support the cab, cut out the rusty metal and weld in new stuff.

If the corners and supports are gone I would look for another cab,alot easier
