I have inherited a 1988 Sport Glide 1340cc. I have had it´s maintenance done and a top-end overhaul. The swing arm has already been turned and I´ve had the seat shaved down, but I still need 1 1/2 inches to have a firm stance. Any suggestions or ideas about where I might able to get a seat that will give that to me? The seat on now is a dual. Any help would be appreciated. (To give you an idea, I currently ride a 2003 sportster that has been lowered as much as it can.) Thanks!
