retro-fitted with the 3 spoke Capri wheels as they were prepped for sale in North America
Actually, although the three-spoke steering wheel looks a lot like the Capri steering wheel, it's different and designed and drawn by detomaso sometime in 1970.
So the wheel had been planned for some time prior to the introduction of the Pantera to the market.
I know that for a fact, as I have the blueprints of the original steering wheel drawing from the Detomaso Design studio (among the rest of the drawings of the car).
My car #1267 is a euro car, and it has the 2-spoke Ferrero steering wheel.
Also note, that there are different versions of that wheel, the detomaso version having "ferrero" insignia on the left spoke.
The one on ebay is the lancia version and has a different insignia.
