1970 Dart Wiper Blade Refills

I am having a hard time finding the exact wiper blade refills I need for a 1970 Dart.

I searched the forum, and cannot seem to get a straight answer as to which blades to get.

I have Anco arms, and the blades are 15"

I have it narrowed down to:

Trico 43-150

and

Anco 20-15

Any ideas?

Thanks!
