Pedal difference?

Anyways
You got it NOW & I say use it & will work fine 3 or 4 speed regardless!
only time this spring thang would be an issue is you EVER NEED BUY that spring !
i find small issue with mopars OEM stuff with same part # YET made lil different !
an inland shifter & seat belts come to mind at the moment for example !
Id waste the rest of your time to figure hyd. clutch mock up ?
Should be smooth left foot relief at red light !
Post pics when you that setup up & working ?
Use what you got for pedal setup & Dont worry about it !
my 2.2 cents opinion on the matter !
