What size windshield wipers am I suppose to get for a 1992 GMC Sierra Pickup?
It is an 18 inch blade. The Trico 18-2 exact fit is a good choice. It is made to install on your truck with no need for adapters.
Take a ruler or measuring tape and measure the actual blade. How come nobody thinks of the easiest solution? Or, drive to the parts store, pop your old blades off and carry them in to hold up to the package. Some of them have rulers printed on the back, but you can line the old blade up end to end with the new one of the right size anyway.
i thought it was ceramic before but i'm not too sure
