They are the ones on my 77 Turbo, and I am missing (1).
Can not seem to find them for sale?

Any clues?
Thanks

I remember about 1990, i purchased a 911 with these on in Sacramento
it was a.. very rough 69 and it had Mahle wheels on it, and those look
about the same as it had, the mounting holes are recessed into the wheel
but i think also those lugs were probably used on some racing Ruf and BBS wheels
or other non fuch wheels, may be hard to find ,i would try older racing shops.
The other thing is could be worth more than standard fuch lug nuts today, because
getting harder to find.

Aluminium or steel?

They are Aluminium, same as OEM.
