Is my 1911 series 70 or series 80?

I'm trying to buy a new grip safety for my Para 1911, and I have to choose between series 70 and series 80. Which one is it? How do I tell?

It's this one:

Para-Ordnance copies the Colt Series 80 firing pin block.

I cannot guarantee parts interchangeability.

Para LICENSES the Colt Series 80 firing system. Saves the time of designing a reliable platform. I have one in LDA! It shoots great!
