If you are "handy" up to 2007 seats will fit, should be easier on yours since it's later than 93. I fit a 2005 Road King seat to an 89 FLHS with little issue. I had to modify the seat pan a little and extend the tongue on the frame for the later seat, but it worked well.
The later model seats have a tongue also, it was a matter of extending the early tongue on the tank so that the seat tongue slips under the tanks. The seat is kinda self centering and the rear hold down screw keeps it in place. It worked like a champ on the 89, did MANY likes with it.
