Gettin close to dropping the motor and trans into the 72 442 vert I'm building and now am really beginning to obsess about things. I did a auto to 4 speed change over and am worried about the 1972 seat belt buzzer and interlock and how it affects what i have put together. I installed a mint 1970 dash harness and I don't see where I have any leads that are supposed to go to that 72 only jumper harness that appears in the assembly manual. I'm not hooking up the seat belt buzzer system at the seat belt dog houses, so if I hook up everything like a 1970 model (clutch safety switch, with short harness extender and using the correct reverse lights switch) will everything work OK without that weird additional harness?
