Ok, starting with that info I realized that I had been looking at incorrectly labelled parts. I was looking at people selling Chevy switches with white knobs as GMC, but the GMC switch is noticeably different.

To answer my original question, the temp lever on the Chevrolet pulls the cable up and the GMC pulls the cable down. They shapes are meaninfully different and they are not interchangeable.

Thank you Bill.
