Which Tuff wheel is this?!?

So I decided to try and put the horn button assembly into my wheel and remove that ugly horn button on the dash, and when I removed the button (which was hot glued to the plate... stupid previous owner), I was greeted with this metal tapered piece bonded to the wheel!!!

The part number comes up as a Cuda wheel on the stamping, but there’s no provision for a horn??? Is this because of the longer can of the E body adapters?

Regardless, I’m ordering a new walnut Grant wheel to replace it, but I thought I would ask as I’ve not found another picture that looks like this center structure on a Tuff wheel.
