I hear ya... it happens. I had an 1989 GM truck that the frame gave up behind the cab, causing the cab to hit the box / bed. But then, it was a plow truck.

my 88s rear half of the frame was like that tha part where the bumper mounts to was almost ripped off i was planning on fixin it but a guy offered me the right price for it and yes i told him that is had a weak frame
he called me back the next day cause i didnt sign over the title right and he was bringin the proper paperwork to get it fixed
i asked him how he liked the truck so far and he said i love it
and he informed me that he was gonna fix it

the police are not returning my calls and im getting frustrated so im just going to part the truck out and hope i can make my money back

i should be able to because everything is in perfect condition besides the frame

you should get your money back and then some from all the parts on that thing
sell at resonable prices and it will sell easy

i threw up a craigslist ad and i have 6 hits already.

im surprised. and a couple people want to buy the whole truck and if they will go for 4000 ill make all my money back
