So I got my Shadow this summer and wanted a trunk too. I didnt like the looks of the ones that sat on top of the luggage rack. There are several generic options on ebay, Craigslist, or other venders. I got mine of Craigslist for $75. The only trick is that it was a 12 inch offset (wide enough to fit a harley) but the Shadows are 3 inches narrower. SO, i easily fabricated a bracket on each side out of steel that spanned the distance and width. Pretty easy to make a cardboard template and it cost me $10 in steel and a few welds and drilled holes, then painted it black to match other tank hardware. I love how it looks. Now I am going to paint it this summer to match the tank and bags.
