I've made pans out of fiberglass for Harleys because I couldn't find any seats I liked or there were none that would fit after I chopped them. After making the pan, which is very easy but messy you just get it covered at a shop. I can't find a seat that I like for my Sporty right now so I'm going to have to make one there. For chopper/bobber type bikes my favorite look has always been the sprung solo seat.
