Throw Out Bearing/Clutch Fork Travel

Hey FABO,

I'm hoping someone can help me with my A833OD set up. I'm swapping it into a 75 Trailduster that used to have an NP435 4 speed.

I'm trying to get the clutch fork throw set, but I'm not seeing the clutch disc move off the flywheel when I have my helper pump the pedal.

How much travel should the TO bearing a d clutch fork have? Right now it's about 1". It's using a short rod though, soi I am guessing I'll need to get a longer rod.
