I have a 91 Harley-Davidson XLH Sportster 883 Hugger and right now I don´t have any tins for it. I am looking into fat bob tanks, found on that is already painted but I don´t know if it will easily bolt up. it came off a 1983 sporty and It is a two tank set up. not sure what all I would have to do to put it on my bike. Any help and info would be great. Thank you. Erin
