We usually tipped the bed up sideways to do the fuel tanks on trucks, pre 1999 models. After that the bumpers were too dang close to the bed, and you had to lift the bed up. SUV's had to drop the tank, which sucked.
That engineer got fired, LOL.
GM did put an access cover in the trunk of their later full size cars so you could more easily do a fuel pump/sending unit, through the trunk. Always nice when the customer kept every shopping bag they ever had in the trunk.
I still have flashbacks doing the oil coolers on Cadillac Cateras and 1st gen CTS's. It sat in a coolant bath in the valley. And the little seals ALWAYS leaked.
And there's always those early 90s W-Body (GM) DOHC alternators. Disassemble the RF suspension to remove.
"Sir, you need an alternator and an alignment for your charging issue."
Not sure on that, I was strictly GM, and have up wrenching in 2011.
The level of stupid then was getting bad enough. I think I got out just in time.
Retractable hard tops (XLR) were fun to work on too.
What a cool project. Looks like raccoons were living under the rear seat. Make sure to hit that with a STRONG disinfectant after you get it vacuumed/scooped out.
Another pic from my strongman competition. We had a guest judge come up from Chicago. Inez Carasquillo. She's a champion strongwoman competitor, and a very nice person to talk with. Gave me some tips on stone lifting.
This pic was taken just after my Conan's Wheel carry, 460 pounds carried in the elbows. I made it 21 feet.
