'66 truck clutch issues

A friend is having trouble getting the new clutch in his truck to stop shuddering. Its a /6 truck and he says he can't figure out how to get the return spring hooked up on the clutch fork right. Does anyone have any info on this set up? Its been a really long time since I have messed with one of these set ups. i thought the return spring was on the pedal on these?

Thanks,

Jason

iirc there is a small hole about halfway along the length of the fork for one end of the spring & I dont remember where the other end hooks to on the bell but here's a BTT for ya

Were you able to get any pics of your set up?

I am sorry for the delay. Work called us out for a small disaster.

Pics tomorrow!
