That looks like a type of lock that was on my 70 911 when I bought it many many years ago. I had to have them cut-off by a tire shop, and they did it with no damage to th wheels or studs. The name of the lock may come back to me but very hazy right now - I'm thinking "McGuard"?. The only other option floated was to make an impression/mold and cast a new key from it, but that seemed like a giant PITA.
Chris, I believe you are correct, "McGuard" from looking on E-bay, Advance Auto Parts and Auto Zone. In the description it claims "•The computer generated key designs allow for an infinite number of key patterns". So finding a matching key is a waste of time.
The problem with the one I removed the stud was loose and spinning because it came unpressed, hopefully the rest won't be so difficult.
Thanks all for the suggestions, the cut off with a delicate bfh path will work.
