nope, that definitely wont work.

Those are for freehubs which post-date the front freewheel system by at least a decade (maybe 2).

since no one seems to remember for sure, you will either have a standard threaded hub that will accept a regular thread on freewheel, or some other type of proprietary attachment for the specific freewheel designed for that system.

can you maybe post some pics or give us descriptions of all the drivetrain hardware on this bike?
