I needed a front fender for my FXD-35 in 2010. Tried your route but HD wants none of that. Turn in your damaged parts for new ones. The story I got was HD want their Anniversary models not duplicated. <shurg> I found a spare fender in perfect shape at the Long Beach CA. M/C swap meet.
A slipping gear could let your M203 grenade launcher
fire when you least expect it. That would make you
quite unpopular in what's left of your unit.
