Has anyone out there installed a spring solo seat on there 03 sporty or some other similair year? I am thinking of putting one on my 03 but do not want to make modifications that cant be put easiely back to stock. My question is how does the bracket for the springs attach to the bike. Do I need to drill holes in frame or fender? Does it use existing holes? I have extra rear fender i would drill into if thats the case. Let me know what cha can. Thanx, Tim.
