I have done some investigation to try to understand the difference between the different A-body pedal sets.
I conclusion that I have come up with is that there were two different assemblies.
In 1969 the parts manual shows 4 different part numbers for the A-body overcenter spring.
- 6 Cyl Std. #2266784
- 6 Cyl Heavy Duty #2461515
- 8 Cyl Except 273 #2883468
- 8 Cyl 273 #2461515
It also shows two different clutch pedal parts numbers.
- 6 Cyl #2781145
- 8 Cyl #2883457
The 6 Cyl clutch pedal used 2 pivot bushings #2467770
The 8 Cyl clutch pedal used 2 pivot bearings #2883462
The picture posted, I believe came from someone here on this site.
The top set I would call the light duty one.
The bottom set I would call the heavy duty one.
