Interchangeable front hubs? Part numbers?

I need to replace one of the front hubs on my '71 911. The hubs are, as far as I know, original. Car is built out as a Carrera RS, I'm using OE type vented rotors and SC (type A) calipers.

The part number on both hubs is 901.431.605.3R. I haven't found any around with that part #. Are there others that are essentially interchangeable with these? I've run across part #s 901 341 065 04 and 901 341 064 06. Are these equivalent? Same wheel bearings, seals, grease caps?

Thanks for any info you can provide -

Porsche changed part numbers but all the non turbo hubs up to 89 are the same. Look at the Pelican part numbers for the wheel bearings. They are the same for 69-89.
