OEM?? ANCO wipers removed from 73 dart sport 340

I cannot tell from your photos but those appear to be whatever Anco used to call their "anti wind lift" blades. The curve is supposed to hold them down. I doubt they are OEM. Show us a better closeup of just the connector. If it is "multi duty" that is a connector that adapts to the blade, or fits more than one, I REALLY doubt it is OEM.

By the way these are just one more thing that really pisses me off about modern cars/ parts. You USED to be able to buy refills (just the rubber) and there wasn't anywhere near the stupid array of different types, although there was some.....

In the mid 70's Anco stopped the "small hook" blades used on IHC Scouts, the original type Bronco, and older Jeeps and Landruisers. The Anco rep's (TWO OF THEM) came to down and I buzzed them about it........they did the bla bla bla with "no call for them."

I told them (it was winter) they better drive through town and count the Jeeps, Scouts, and Broncos and then come back and tell me that.

We had to buy them from Trico!!!
