I was going to do the whole cut down the sissy bar and change the seat this winter, but my bike had a one piece mustang seat. I have already cut the back rest off and i was going to attach a piece of flat aluminum to the bottom of the seat and bend it down to the fender. Then drill a hole in the aluminum and the fender and through bolt it with a acorn nut, for a nice finish. Then i found a stock seat in almost perfect condition on craglist. The guy didn't know what it went to so i got it for $60.
i will try and take some pictures tonight of what i have mocked up just to give you a idea. i still may do it but not this year i can save the money for other goodies.
