wiper arm replacement 2005 silverado
 

I'd like to replace the OE wiper arms with ones that will pull up and stay off the glass inorder to swap blades when needed, and also to keep snow off, while parked out side. Any suggestions?

Great idea... It would be real convenient to be able to raise the wiper arm to replace blades and to simply raise the arms when you know that evening it is going to go below freezing to avoid the blades from freezing to the wind shield.
You will be lucky to find that similar vehicle with the same size wiper shaft and with the same spline count.
Good luck
Let us know if you find a combatable vehicle.

I don't think the aftermarket has wiper arms for this purpose, but doesn't a silverado/Seirra already have arms that do that? I can't recall if my '96 does or not, but I was pretty sure most/all of them did this already.

My 97 arms fold out

No the 2005 does not , (reason I posted this). My 03 Dodge Ram did,
01 Blazer did as well.
