Re: Hi De Ho Motor-o's I'm done lurking !
Welcome and there are mounting kits on ebay for the choppers if you want to go with them. I know how you feel about messin' up a perfectly good bike. All my bikes come from the thrift store. That was if I screw them up and I usually do, no real loss to the world of biking or my pocketbook.
Good luck and you and your mechanic friend will love those bikes.
