My truck had an older BD exhaust brake on it when I bought it. It also had a lot of other aftermarket accessories, most of which were obsolete and poorly installed. So when I initially got the truck, I removed everything that was not factory installed. I saved all of the BD Brake components though. Now that I have the truck pretty well sorted I'd like to reinstall it. The vacuum lines probably need replaced and it will need new wiring but I have all of the components. Anyone here have one, like it, use it? Are parts available? Thanks!
