i used a fatboy fender on my heritage fatbones conversion.the tombstone light will NOT bolt straight up your right the recessed area for the light is to wide to be covered by the tombstone.i had mine welded up and i re-drilled the holes for the tombstone.yes you will need to relocate the signals to the rear strut mounting hole
heres a few pics

 

Pulling up an old thread. "sorry"

But I am about to do this.

• "colonelangus1" did you put any indention into the fender to fit the tombstone light, or does this sit on top?
• And which tombstone light did you choose?

Thanks
