The rack you are talking about uses the the holes in the fender filler for the permanantly mounted brackets. Best bet is to relocate your antenna to the inside of fairing. I tried that rack but figured the scooter would look like a ski boat with those brackets hangin off the *** end. I'll tell you something else ---- be ready to do some serious saddlebag aligning after you start un-bolting things from the rear struts. Things start doin the hoochy coochy when you remove those bolts. Take your time, dang sure don't pay the shop to do it. It's not that big a deal, I just think so because I ended up not installing that rack!!!!!
