I am about to move across country and need to replace mine before my drive. I have been to truck stops and auto part stores no one can seem to help me with this.?? I've never had this problem with any other Chevy vehicle I have owned but I havent owned my truck for so long so I am not sure if this is a special model or what the issue is!! Please help leaving in 2 weeks and need these replaced!

 

When I look it up on Rockauto it looks like a standard 22" blade to me... they are listing the same blade back to 2003 Silverado???

 

Welcome from Florida. I have a 2013 Silverado and have changed my wiper blades several times with no problem.
