Sorry for the lack of response. I am pretty sure I have the original Anco windshield wiper frames. I have replaced the blades before for 16" blades, they don't really work too well and hang off the edge an extra inch. IIRC, I think a fried of mine at the local car show gave me these metal inserts.

Since, I just happen to drive by an O'Reilly on my way home today I checked to see if they had the TricoClassic blades and they had two. It looks like a better quality than my blade; however, I'm not really sure how they attach and don't want to fiddle too much with them in case I need to return them.

So, how do these fit on exactly? It seems like mine have a tab that locks the blade into a fixture where the new ones have a spring clip of sorts.
