interesting;
so the “1972 only” pedal assembly #3998671 was only used from December 6, 1971 through to February 14, 1972 - This is a little over two months!(?)
I wonder if the change to the “1972” assembly was something as minute as an assembly with an additional hole for mounting a wire assembly associated with the seat belt warning.
I didn’t speak up earlier, because I was stumped at the assertion of a “1972-only” part;
I figured that maybe I would say something after someone more knowledgeable than me speaks up…
At a glance, the assertion of a “1972 only” part doesn’t quite fit in with the way (that at least I have perceived) GM to do things…
I too had understood that the clutch pedal was the same one used for 1971.
Maybe the part number revision was something as small as a supplier change??
Wasn’t the assembly a combination of parts(?);
The mount was the same for auto or stick cars;
The “assembly” was the combination of the mount, brake pedal, and (in the case of a manual transmission) a clutch pedal.
