pictures of pedal assemblies 340 vs. others

I have a somewhat related question....

I am putting together a 4 speed pedal assembly from a box of parts. How is this sub-assembly supposed to behave when not installed in the car? Specifically, what I'm talking about is the function of the over-center spring. I thought that as I would move the clutch pedal down and up, that the spring would try to bias the pedal into either of these end locations. What I'm finding is that the spring wants to pull the pedal down, and if I pull the pedal up it is extremly unstable like a mouse trap (and a hell of a lot more dangerous!). Also, the spring pulls the pedal down such that it's bending the start depression switch bracket.

Have I done something totally stupid, or overlooked something simple? Any help would be appreciated. Thanks.

My '74 was like that when I bought it, The pedal was jammed against the floor and the spring wouldn't let it move. I had to cut the spring in half to remove the pedals from the car, that's how tightly wedged to the floorboard the clutch pedal was :wack:

My '74 had a later style Pedal Assembly in it when I bought it. (wasn't original though, since it was originally a 318 / 904 car.)

I yanked it out (and cut the spring in the removal process) and tossed it on the shelf. Now I'm getting ready to swap a 4-Speed in it, and My later style pedals measure 6" pin to pin spread (no brace unlike the 340 pedals in oldmanmopar's pics)

What's the deal with that? Did somebody install earlier pedals in a later "cradle" / Mounting Bracket? What's to keep my pedal from jamming against the floor again (with the spring installed) when I convert to 4-Speed. My options at this point are to buy a new spring from Brewers, or forget about the spring and go with a Diaphragm Clutch? Right?
