Hello, very new to the Thunderbird world, and as my name shares, very senior to the rotary world. My son decided he wanted to get a Father/Son project going and we have purchased a rust-free 1966 Thunderbird. While it has been great fun so far looking up/breaking down the VIN code, it is now time to start getting the vehicle running. While we are waiting for our shop manual and other items to show up, I went to go look up replacement parts for the Brake Booster and Master Cylinder, and this is where the confusion starts. When I look up the parts there are two different types: Bendix twist lock unit. With master cylinder Midland Clamp Band Unit. With master cylinder Since I haven't taken the old one off the car, and not being very familiar with the Booster units, is this two different styles that it attaches to the car, or maybe different ways to attach to the MC? Is there a preference of one over the other, or am I stuck using the same one that is one the car today? I'm going to pull the old one off the car, tonight maybe, and will hopefully figure it out, but I thought maybe that while I was sitting here at work being bored someone might enlighten our naivety in all things Thunderbird. Thanks!
