Hi Joe,
nice project you have there. Indeed it will be very difficult to get the headlight shroud from the Fat Boy. If you search at the bay, maybe youŽll find a junked Fat Boy, or you buy a new one and change the upper frontends. And donŽt forget to make the gas tank smaller than the original FLH. For the rear Fender I think its easy to chop the rear fender from the FLH. Good luck for this built.

Please show us one more pic of the original from the other side.
