I purchased a set of wiper blades from jim carters. The connection is much differetn that the old blades. My wiper arms have a slight offset at the end, with a drilled hole. The old blades were looked more like a new style blade. The new blades from Jim Carters are a think blade, with a very simple stamped sheetmetal tab. Can anyone send me a picture of their wiper blade/wiper arm for a 40 - 46 GMC/Chevy truck? My home email is [email protected].. Any help is appricated.
