Sorry guys. I don't think that's right.
At least through '69, cars could come with either Anco or Trico.
Neither the NAPA nor the Trico refills are correct replacement for the pushbutton series used back then.
Post up the Chrysler p/n for '70 and I'll post up the ones from '67-9 so we can compare. Just blade and refill numbers.

FC70 - post some photos. It will help clear this up. Also, measure your current blade. If its an Anco pushbutton series, the length is limited by the claws. Trico I don't know, but it will be close.
