Wiper refills

Hi y'all:

So I'm having an issue with finding wiper refills for my '64 Val, I've got the ANCO stainless steel w/ the red detent. This may be a given, I don't know. I searched archives and somehow figured the ANCO 12-13 or 11-13 were the ticket, apparently not, an old timer at the best local parts house said I wanted the LP-13 (off the top of his head, not like the young gal at the other place who asked "What's a Valiant"). Anyways, anyone know what works best?

TIA

Dan
