I gathered the information directly from the Pontiac service manuals. I agree that depending upon the timing of publication, some of the codes may have changed, but were authored by GM and considered accurate at the time of printing.

There are separate codes for auto and manual for each configuration, due to the trans cooler tanks. I will double check the code published for the '69 with A/C, thanks for bringing that to my attention.

Kurt, reading your page, the diameter of the four blade fans used on Ram Air Firebird and 396 Camaro is larger than the diameter of the four blade fan used on the L6.
