Wiper Blade Search

Hey FABO, I'm trying to find some new wiper blades (just replacement blades, not the arms), and I see a lot of reference to 15" Trico and Anco.

Mine measure about 18.5" from tip to tip.

Anyone able to tell me what I should be looking for?
The wiper arms have an Anco stamp on them, not sure if that matters for fitment of replacement blade.

Thanks for the help.
