Once upon a time I bought a '96 triple locked from a dude in Portland, Maine. I didn't walk into the purchase with my completely eyes shut so I knew new rockers were needed and the seller pointed the camera everywhere I asked him so I can never say I was scammed. I drove it back from Portland to Orlando with no issues except for the smell of gas when I stopped for a refill.
Back home I found that the fuel tank filler tube was destroyed with rust. Knowing I had to lift the body from the frame to replace the fuel filler tube, I soon discovered the tank was basically a sieve. From there the rabbit hole was deep. Pandora's box was flung wide open with viscous consequences.
My rear quarters were as bad as yours. The box section that runs across the back where the 2 rear most body mounts attach was non existent. The carpet was destroyed but when I removed it driver and passenger floors were MIA.
A wise man would have scrapped the vehicle however I am not wise but did have a welder and lots of time. I spent over 1 year on and off cutting and welding new metal. I bought new outer rocker panels but had to fabricate the inner panels. I made new floors. I rebuilt the complete back end where the body mounts go. I rebuilt the lower portions of the quarter panels from the top indent with new metal.
Nothing about the rebuild was easy. When you cut away the rust you are left with galvanized metal which is a bitch to weld. Wait, did I say bitch? I meant to say Cünt. To date no tool has been invented that allows you grind the parts other tools can not reach.
5 years later the truck runs like a champ. My daughter has used it as her daily driver for 2 years. My son and I did a road trip from Orlando to Montana and back last year and are planning to hit Prudhoe Bay, AK later this summer.
Is my truck great, well no. Rust never dies. It does something to the metal that I cant explain. New bolts will start to rust for no observable reason. Paint will bubble where rust didn't previously exist. It never ends.
My truck is mine and I have had many days of enjoyment from her but if i had to do it again I wouldn't. It is just not worth the fight and rust always finds a way to win. @Godwin suggestion of finding a doner frame is the only practical advice here. Rust will destroy you. Move on quickly and find happiness.
Good luck
