Quick update. The radiator and tank shop that did not take the blame for damaging my tank is City Radiator in Levittown, PA. I ended up sending it to Tom Craig Radiator in Palmyra, NJ, and had it back and repaired in two days. Still waiting for the body shop to finish repairing the physical damage that the first tank shop caused.
Here's how the bike stands with the chopped and painted fender.
