Hi Again Bill,
You'll need the MemphisShades mounting kit for the Suzuki Marauder 800. Kit#9907 (i think). I found a new one on ebay for less than $50. After installing, MAKE SURE you check your clearances between the bracket and gas tank. I learned that one the hard way. I was nauseated for the rest of the day when I saw that small sharp dent in my perfect 2.5 year old paint. Sickening.
