Hello, I recently took on a GM parts department (came from Ford), and this may seem like a stupid question, but what wiper blades do you guys recommend keeping in stock? I can't seem to find an easy way to find a list based on various lengths. At Ford, the length of the blade was essentially part of the part number (WW1201PF, WW2601PF, etc). I can't find a rhyme or reason to GM's part numbers. Help!
Thank you!
