@RagTop66 It's pretty much covered in post 20 of this thread. The booster is in. It was quite the battle but I persevered...along with the stoplight switch. As you'll notice, the original switch was replaced by hacking up the bracket to fit an aftermarket switch. Less than stellar results, no doubt the work of of Larry, Moe, and Curly. Booster... Bracket for the proportioning valve mocked up Miz Ruby was a bit Ms. Rue today, she beat me up pretty good.
