I'm not sure how much this helps but the GM number you need is 7293476 (AC Delco number 15-7191) and I can only prove it fits 66-67 Beaumont and Tempest/Lemans/GTO.

I should mention, I suspect it will only fit the Lemans series if the car has no A/C. Your switch is 3 speed, right? It seems to me the A/C cars have 4 fan speeds.

Is it the same as a 64-65.  if so i probably have one.  can anyone confirm?

You are right.   the 67 is different,  arm has a different bend and the pin config is different

This is the only 67 one i have but the back pin is loose.  it works, but you would have to take it apart and repair it a bit.

Dave, 64-65 has the same number of terminals I assume? That would be a simple thing to work around. Does it mount the same?

I compared the heater control housings and they are different!   64/65 is flat and 67 is angled, so the switch sits on a different angle thus the lever is tilted on the switch itself as well as the terminals being in a different config,   those 1967s,  millions of differences over the earlier years!!!

I suppose 66 would be teh same as 67, but i dont own a 66 and never have.
