I have two pair of hubs for my 914-6, one that is original and another pair I got at a later time. I'm not really sure which is which or what the difference between them are. Anyone know what the difference is? Here are some pictures and part numbers.

911.341.605.4R (appear to be cast)
901.341.605.3R (lighter weight and smooth)
Thanks,
Bob
