I thought I figured out how to stop the intermittent buzzer issue by disconnecting the door switches, but no. Can I just pull the buzzer out and where is it? I'm guessing g its on the fuse panel somewhere

Make the buzzer come on. Follow the noise. Pull it out. Throw it away.

Use deductive reasoning? I was hoping to not have to work that hard.

Round silver relay in fuse panel. Usually has a red bottom. The rest of the relays are black.

That's true for the 1970-73 cars. Its the small cube 'relay' mated to the side of the seatbelt interlock "relay" under the passenger seat for the 1974-76 cars.
