Would someone kindly give me a hand installing the clutch?

Which way does the clutch disc go in? If I am reading the manual correctly the nipple side goes towards the flywheel.

I am installing an engine from a '51 car into my '52 truck and it looks like the car owner had the clutch the other way around. And also they used the wrong flywheel bolts and ground off the heads and ruined the clutch disk.

Many thanks!
