I have vstar 1100 and recently bought some bag supports off ebay. they didnt really have instructions but did have all the mounting hardware. Since i had a rear sissy bar and luggage rack, it had some hardware installed already.My holes aligned with the bolts going through the fender ok, i didnt have to drill anything. Hope you can make them work. I had a real bad experience with not useing the supports. My saddlebags rubbed the rear tire and cut a large hole in them. I was able to repair it using some info i found on a biker forum thankfully. i learned a hard lesson, i shouldnt have used the bags without the supports I guess, my right scraped the tire the most. The supports have eliminated the problem, hope yours work well.
