Well, I could use a bit of help here. My '63 C20 has the optional windshield washer. I have yet to test the pump, but I was eyeing things just in case I do need to replace it. Now, there is no replacement listed for a '63, however, there are ones listed for '64-'66. So, if any of you guys have a '64-'66 with a windshield washer pump, would you take some pics so I can see for sure if the pumps are the same? Or if one of you knows for sure that they are the same could you let me know? I am thinking they are the same, just minor variances, but I would like to find out for sure before I shell out money for something that isn't going to work.
