I picked up a wiper motor and arm the other day off of a friend, but it didn't have the blade with it. The wiper is a Wilcox & Crittenden. The end of the arm is half moonshaped with a 1/8" wide by a 3/8" long slot in it. Do any of you guys know of a supply house that sells these. If not I'm supposed to call a guy when I get off of this computer to see if we're going to Louisville. If we decide to go I'll pick one up there. Thanks. RRM
