Wilwood aside, and short of machining on a lathe or going medieval with a grinder, has anyone seen a source for OEM type disc brake rotors (typical early 70's and up, 11") that have a beveled nose on the hub?

99.9% have a square nose. Dr. Diff has a photo of a beveled nose rotor but doesn't actually possess any with it. My searches have come up empty so I'm thinking they're like unicorns.

I have Dr diff rotors and they have the bevel just like your picture

I went with the medieval option. Pulled them off, plugged both ends, and went to work with a 4" grinder. Needed to in order for my Bullitt rims to fit.
 
I’ve seen them before but not recently. I have one “pair” from the same company, bought at the same time from the same place, that had one of each kind. Seems like something you’d have to actually check in person
 
I ordered a set of rotors from Auto Zone and got one of each. I ordered them for a 85 Dodge Diplomat. Don't know if you have AZ in your area.My local store has no problem if I don't want a ordered part.They ordered again, I got a match the second time. Maybe you will get lucky.
 
Easy peasy. Chuck it up backwards on a brake lathe. Mount the drum brake arbor on the machine, but flip it around backwards so the bit points toward the work. You'll have to work both cranks to manipulate a bevel, but it will be cleaner than a grinder. I've done it a few times just for the reason you describe. To clear center caps. It doesn't take much to get it done.

Got an Autozone here buy not a lot of confidence in them.

I'm not a brake lathe operator but will see if I can find someone willing to do it.

Are you "in good" at a local O'Reilly store? You might try and see if someone there would be willing to do it. I would not let them touch them though, unless they were OLD and acted like they knew what they were doing. lol I wish you were local to me here, I would be glad to do it for you. I know that's pretty useless, though.

Ha! Not in good with the local O'Reilly's either. They're all punks - but I appreciate your offer. I'll talk to an automotive machine shop I've done business with.

Keep this in mind, too. It does not have to be a bevel. As long as they can machine it down smaller then the end is, that will do it.
 
As a follow-up: The auto machine shop has a disc only lathe he says won't work and won't touch the old drum lathe sitting next to it. I went to an industrial machine shop and they're telling me about $100 to cut 'em down - so, that's where I might end up.
