WINTER wiper blades for 2007 Silverado NBS
 

I have a 2007 New Body Style Chevy Silverado and wanted to put WINTER wipers on it since we have had bad weather here in PA.
I found out Chevy has changed the Arm and Blade style on this truck, NO ONE makes WINTER blades for this truck (ANCO,TRICO, etc) unless someone out there knows if someone does.
I call both ANCO and TRICO, ANCO said their working on it, but not to expect anything for several months.
Maybe someone can tell me why Chevy changed the style, just to give heartaches to customers?
I called my local dealer, thinking maybe I could change the arm to accept winter blades but was told it wouldn't work.
Very frustrating, anyone have any suggestions, I would appreciate it.
Thanks.
