Hello out there, inliners

I am in the process of building up a P-24 1954 Plymouth 218 CID Flathead 6 engine.
I bought it as a “rebuilt” short block.
I would like to supply all the necessary parts to have a complete engine when I’m done.

I have an old, run-out T-137 Power Wagon engine as a parts donor.
Some of its internals are from a P-15 1948 Plymouth. Since it was removed from service 15 years ago, I don’t remember exactly what is what. It all started when the machine shop cracked my P-15 block while pressing in sleeves. But that’s another, sad story.

I have a question about the crankshaft Hub/Pulley Assembly:
The old engine has a steel and rubber bonded vibration dampener, which is keyed to the front of the crankshaft, to which is bolted the v-belt pulley. Can this style hub be used on other year engines? I want to use it on the P-24, with a starting jaw/nut.
I see the MoPar parts book shows it used on only some models. Does anyone know about compatibility issues?
Thanks for any advice you may have.
