Daryl, if you get a chance could you get a picture of the rear fender with the seat off and also a picture of the underside of the R3T seat. There has been some talk of trying to get the R3T seat and put it on the Classic and on the face of it, it is not possible. Something could possibly be engineered to make it fit, but it will take some work. The R3T seat has a hole in the rear fender for a pin from the seat to insert into it and it also is bolted in the front with two bolts...one on each side. The attachment set up is nothing like the Classic or the Stock Rocket.
