First I have heard of it, but looks to be a Ford recall part for the Capri steering wheel so could potentially be fitted to the oem Pantera wheel. But from the description it's function is to prevent the steering wheel fully collapsing and I don't believe the Capri had a collapsible steering column like the Pantera

Question:  Are there two “collapse features” on the Pantera steering system?  

The OEM steering wheel mount body is made of corrugated sheet metal, and of course there is the collapsible shaft…

I don’t know if the wheel body is a safety feature, or a styling element…

This is the reply I received from the seller when I inquired about the installation.

It s truly very simple. No diagram, but you put it inside the steering wheel barrel, and then tighten the center bolt until it expands to seal against the inside of the barrel. Boom, done!

Digging a little the Ford steering wheel safety recall for the Capri was 1969-72. There is no such recall for Pantera's that I'm aware of and as the issue was identified prior to first Pantera production I think it was likely resolved with the addition of the collapsible steering joint (lower section) which was not included on the Capri at the time.

Thank you Joules.

This is an interesting sketch on the subject.

Wiper notes: Our '72 L came with the dual plated wire blade-holders that were also used on late '60s Jaguars. The arms that pivot on the protruding stubs were Trico which may be U.S-made (Ford). The serrated stub size seems to be standard for many cars around the world including U.S-made GMs.

Many Pantera owners carry the wiper arms & blades loose in the front trunk. One Nor-Cal owner who drives "vigorously" once had an electrical fire when a loose wiper bounced up and shorted across the stock-mounted battery posts! There was some hood damage and it melted part of the battery case, which leaked acid. If you carry the wipers in the trunk, I suggest cloth-bagging them, or drop the battery down in the front trunk ala post-'80s Panteras, with a cover over the terminals.

Back in the day, wipers were well known to lift off the glass at speeds above about 125 mph and tear off, which may have led to storing them in the front trunk in dry locales. The Euro-Pantera Gr-3 Catalogue lists small sheet metal clip-on blades that hand-slide onto stock lower wiper arms and act as 'wings' to prevent wiper lift. Hall used to sell them but I've never seen a pair except the ones on our car (tested to 150 mph).
