I know a couple of you guys have installed the Sundowner. I know it's not very hard but it seems like I'm missing a bracket. I have the Solo Sundowner with the detachable passenger pillion. I took the bracket off the stock seat and attached it to the pillion but do not have a way to attach the solo seat by itself. The dealer and instructions say that the bracket for the solo seat is standard with the FLHR. It wasn't in the box and they can't find the part # for it. Any info would be appreciated.
