The only place I’ve ever seen any Bulldog Bagger saddlebags was on a rack at HDM. Call Eric @620-680-0395 to see if he has any left. I’ll bet they are hard to find, as BDM didn’t make very many Bulldog Baggers—about 120 total in 2009-2010. Mounting hardware would also be an issue—you’d have to drill and tap the fender struts, and re-wire the lights to the ones built into the saddlebags.
There were a couple of posts a year or so ago about a member who adapted H-D style bags to a K-9 (I think). You might do a search for that. I don’t know who could match that beautiful paint scheme. Maybe Airbrush Ed, who works for BDM in Wichita, KS. He painted a lot of them for BDM back then. Good luck and please do let us know how this project goes for you,
