One more thing, as a novice, little patience, does all upgrades and fixes using Google, and small attention span to detail, I did the quarter panel fold in the back. Being that everyone else makes it look so simple and clean, mine had a few spaces I bet mud and water would get in to, so I bought the 3M Bondo stuff with the mesh cloth and sealed as best I could the cracks/rust holes/crevices. Hope that should do the trick. Also, the electrical nightmare I was having described in the thread above, was the result of rusted out 1/4 panel that was allowing mud/water/salt water from snow to corrode the wires. Had to have it rewired. Figured the quarter fold would be the way to seal it from future issues with electrical wires.
