Since I took off my saddlebags and changed my seat (2015 Phantom), I've lost all my storage. The Blue Collar Bobbers seat is bolted in the back with two bolts. I was thinking of maybe getting a small round tool bag and bolting it the seat bolts, probably with some flat aluminum in the bag for strength. Has anyone done this? I'm must looking for a place to put my registration, glasses, and phone.
