So the vendor is sourcing this new design from Luisi now.
It is very similar to the Momo 8000....for the early (70/71) 914-4.
Classic Garage is the place.
I think total including shipping is right at $85, so a very nice price.
Not affiliated.
They just went out of their way...a lot...to help me out.
https://classicgarage.com/s5904.htmlAs far as horn buttons go....
There is a supplied ring that can be used, but I think a standard Momo button may still be too small.
I've got a horn button I bought from Car-Bone out of Poland that fits nicely with a little foam tape on the edge of it inside of the supplied ring.
I'm sure you creative guys out there can figure something out.
Otherwise, everything else fits as it should.
The stock cancellation rings mounts up easily.
The horn contact pin is in the correct location.
The splines are correct.
And there is the right amount of recess on the backside of the hub to meet up with the steering column with a small gap between the two (the hub and the column).
I'll try to get a pic of this hub up on this thread by tomorrow.
