GMPartsgiant, GMPartsdirect & RMSAuto are showing these available. I'm not sure if a local $tealership will have them in stock, but it's worth a shot.Fuzzcar
What a coinky-dink. My drivers side blade won't stay put and it's raining today; can't go to work until I fix it.
I thought the wiper arms were 22" for both sides. By chance do you know if these parts are still sold at the dealers?
