@jimgmc - that is an interesting diagram and image. In the picture there are 2 pins and they are threaded into the block.
It's still a bit of a mystery to me. The diagram implies that both springs are attached to one of the pins. And your response may imply that the other pin is only there as a stop pin. This would make sense to me because otherwise the spring would pull the gas pedal down instead resisting the gas pedal.
I wonder - do you have a pic from the other side of the exhaust? It almost appears your linkage is either different or upside-down from the diagram.
Incidentally, Jim Carter sells a Chevy version of a spring and tab - the tab would be held by an oil pan bolt, and the combination would pull down (vertical). I ordered it - just seems to make sense.
