4-speed pedals Heavy Duty

I am quite familiar with the differences. Hard to come by? So you’re saying there is a market for the ones that I have and I can basically name my own my own price? Thanks for the heads up, I will certainly consider this.
Im not getting my head around why this spring is removed? I can see where it may not be needed. Thus just wasted push needs. But I have read some posts that it can hurt the clutch?
