yes the fender off a heritage will fit on a fatty. But if you go with the Heritage front fender it will have mtg holes for the chrome trim and light in the fender tip. But a front fender off a FLH will not because it is too wide. Look on the Ebay there are all kinds of raw fenders, you might find what you are looking for. Good luck.
It's a direct bolt on.They sell a FL clean front fender for the softails in the Harley catalog,part #59054-96.Listed at $150.00 in my catalog,but that's back in 2005.None of the holes for the Heritage badging to worry about.Here's a pic of one on my 03.
