4 speed Conversion kit questions

bought a complete auto to 4speed conversion. It was a kit from Norms and it appears to all be there.

This was 71-74 B/E body big block kit with 10.5 flywheel.

Decide against the 440 build and Bought a built 340 6pack (forged crank internal balance) and trying to figure out what will work and what will not.

Is it just the Bell housing and zbar the only thing I need to replace with Small Block parts?

What about clutch fork? Any thing else??
