Try these guys-
www.rightstuffdetailing.com . I met the owner about 10 years ago, when they were still kinda new. Top notch guy, and he has done well with his business. They didn't make a kit for my 3600, so I had to get one from Classic Parts. Guess what? It was wrong, and they wouldn't do anything about it because it came right from the supplier- inline tube.
At any rate, deal with the maker directly, screw the middle man. I highly recommend that you try the above website first.
