Hey Red,
I've got a pair of front drum/hub assemblies from my recent disc upgrade on a 54-3100 straight axle. Don't know if they are the same as on a 50 but you're welcome to them. They had the rivets that I ground down to get my 6 lug aftermarket wheels to fit flush. Also have the original ball bearings that are in decent shape.
I'm headed north on I-95 next Monday (31st) and would be willing to drop them off. Let me know.
Dave
