Thanks Rick. I bought the unpainted trunk and mounting bracket off of Craigslist (package deal). The bracket was for a Vulcan. The width was correct, but I needed to grind off the spacers on the inside of the bracket arms, since the Rocket fender had spacers there already. Also had to redrill the front hole to match the Rocket, but that was just a minor 'adjustment'. The trunk was well made fiberglass with a large plywood base for reinforcement. I've attached photos of the bracket from underneath and the arms. Also the back of the trunk. I added a bright LED running/brake light to the rear as well as the reflective Triumph sticker.
