Yeah the ones on my truck now are from NAPA, same part number I used at the same NAPA, they came back with a different wiper that didn't fit.
NAPA Wiper Blade Replacement
Bought those in November 2016
Since so many things on this truck are Chevy, but not always 1965 Chevy... when I find something that works, I keep the box top with the part number for future reference.
Checking out the NAPAonline.com site, seems there is a new part number that is supposed to fit, but I have not seen it in person yet:
Part #: WIP 60131
Line: NAPA Windshield Products
