this is a side pic of the warpage, the other side (drivers side) is flat on the sheet of glass, the pass side is that high off the ground behind the front wheel, that's why I say its slight warpage, but it does bug me enough to wonder if all the building and painting then assembly to have 1 wheel not touch the ground. I will mock up the interior and all the chassis parts and see what it looks like. I may try the hot water treatment one more time too.
