When I had my Road Glide I knew that I could change out seats from any other bike in the Touring line. I don't think this is possible in the Softail line but would like to confirm.

What other seats can I put on my '19 Heritage? Will seats from other models in the line fit, and if so, which ones?

Thanks in advance, and ride safe,

 

 

WE know there are different frames and gas tanks for the M-8 softail models. Seats are interchangeable between some models, but not others. For example, there are three softail "tallboy" two up seats
one for FLDE, FLHC, FLHCS, FLS, and FXBB
another for FLFB, FLFBS, FXBR, and FXBRS
still another for FLSB and FXLR

Unfortunately, there is similar uncertainly about mufflers, headers, and other parts, both OEM H-D and aftermarket. This probably doesn't help you much, but there are no simple answers.
