Clutch pedal will not come back

You probably have a 6 cyl. or late cutch pedal they are totally different then a early or 340 pedal or V-8's. They have a baby spring on them. because they only have a 5 1/4 pin spread. There is also an extra brace to hold the stronger spring on the early 340 pedals.
If your going to make sure of anything make sure you have the correct pedal assembly for the fork your using. Short throw pedals short fork. long throw pedals long fork. I have them out if you need pictures

I have had 2 pedal sets in my car, one I pulled from a 318 duster, the other came from a '67 3 on the tree slant car cause I wanted a 67' pedal pad set and they were still clean and black painted unlike my 73-74 set.
Both pedals have the exact motion/ratio, and both came back up all the way, so what am I supposed to think?

I do not have a '340 pedal set', if it's really different...why they would bother with different pedals within the same body I dunno..

You're gonna have to explain that one to me, if you don't mind?

The other thing would be this, if so...how is it my as you call it ''baby spring'' able to lift the pedal while this bigger spring can't?

or is that the ratio's fault?

Just thinking about this cause I have never heard anything beside diff pedal assemblies for early 61-66 cars and changed in 67 then 71 & up 'pedal pad styles'
