Picked up this seat from a friend and he has no clue as to what it might fit.....after spending a couple hours on-line trying to figure it out I thought I'd have you "experts" chime in with your opinions.....this seat is new with the sissy bar held on by 2 acorn nuts at the rear of the seat.....the only numbers I found on the underside of the seat are : RDW 92/61-0067. Cross-checking these numbers with HD...dead-end. punching these numbers on e-bay comes up with a variety of different seats sundowner, solo....etc. Any help would be appreciated. BTW this seat will be up for sale if and when I can figure just what it will fit.....Thanks guys!
