I bought Kmrmike's tour pack from him for my touring, Just got it back from the painters. Ottawa Valley Custom paint did a great job matching the color, cause we all know how hard it is to get a paint code from Triumph (impossible).

As far as mounting, I'll post some pics later, But it Looks like Mike removed the passenger back rest, cut some steel tubing,drilled and tapped 4 holes so the original 4 bolts worked to secure it. I have it mocked up right now, I'll take it apart and post some detailed pics.
