I've had several of these trucks apart and haven't seen that patch on any of them. But, all of the ones I've taken apart were Stylesides. So, maybe it was on Flaresides?
Dave/Fuzzface2? Have you seen that?
There should be at least one Flareside at the show on Saturday, Cash's Carlos, so I'll check it out.
