Will a heritage fender bolt up on a fatboy. 2006 model? I have a fatbot but like the look of the biger fender. Or for that matter even a road king custom fender?

 

Also will the HD deluxe seating also fit a fatboy?

 

It will fit. The only issue will be the front marker light on the Heritage fender - you will need to run a wire down if you want the light to work, since FB doesn't have that market. A Road King (touring) fender will not fit, I believe.

I am actually doing the opposite swap

 

I believe it will fit. We did a swap on my brother's 06 to a Heritage seat - we had to add some bushings to the right and left side receivers that were already there on my Heritage, but that was it.
