Here is the rest of the story. Undercoating removed to expose the spot welds . . . . .
Thanks for the extra pics! I'll have to remember that trick. I don't think I'll have a problem with my drag wheels/tires, but the roadrace setup may get a little 'snug" under there. Plus, since that bracket just spot-welds on, I think removing it skates around the "unaltered frame rail" rule.
