LOL I am attempting that right now! I had forgotten that I have the Detroit Iron online 65 Pontiac manuals which also has the AC system manuals, and I'm reading the section: 10-1 Services and Repairs - Mechanical right now. Page 10-5 says that exact same thing.

I currently have a small 1/4" socket on the head of the screw that connects the diaphragm bar to the defroster door, but before I go any further I'm going to look online to see if I can even buy a replacement Delco-Remy diaphragm (everything is on the car, console still in but driver's seat and steering wheel out since I'm doing all the dash work).

Thanks!
