TTI Headers on a 340 in a 65 Dart

Pics would be good. Maybe with power brakes? I see a booster with an angled bracket that elevates the system offered online. Anybody tried that? Just would like to get an idea before I order the parts and then have to send them back, or worse yet, sit on them for a while. I know the early a does not have much room but only to shoehorn things in a limited space......therefore, the questions. Thanks again. Old Dart 66.
