Source for Snap-off quick release hub?

Does anyone have a source for the Snap-off brand quick release steering wheel hub and adapter plate used in a Superformance GT40?

I solved this issue by making an adaptor plate with the 6x74 mm pattern bolting it to the Snap-Off boss and a 6x78 mm pattern for the wheel.

Nice work!
Doug,
the pic you posted about the snap off looked strange to me - on my Superformance it is a slightly different design. Please find some pics.
The diameter on the steering wheel is approx. 78mm

But there is also a adapter plate between steering wheel and snap-off

When mirroring the 78mm diameter to the underside of the snap-off it seems too big

See also additional drill holes which seem to be drilled afterwards (seemingly to attach the adapter plate)

A 70mm diameter seems to be right

Verdict: the factory snap-off should be 70mm with an adapter plate to 78mm

Your snap- off hub looks a little different than the one Fredrik P posted above.

Yours has some sort of key?

I agree. I need an adapter plate. Unfortunately, I'm no machinist.

Earlier cars had a key to lock the wheel on and two "mushrooms" to release the wheel. Later units have no key and two flanged stems to release.
 
So apparently there are differences between the models of quick release hubs offered by Snap Off.

Some have random pin placement for security. They don't allow for interchanging different steering wheels.

As I want to be able to use both my existing wheel and the new one on the same car, I need matching pins. One more variable...
 
I have one of you are interested in it

There were 2 different versions of the removable steering wheel used on the Superformance GT40.
I believe the owners manual reflects both styles.
