Eugenio, original Pantera wiper arms 1971-up were common to 1969-up Jaguars and possibly other English cars of the time. They are stainless steel or nickel plated 'two-wire-style' arms rather than a single flat blade common nowadays. If the numbers in your 'avatar' are correct, both your Panteras are pre-L models so the wire-type Jag arms are what you want.
