hello out there i need a little help with my wipers. I have a 49 3100 with a 350. the paint job is almost done and I was getting ready to start shopping around for the interior when I realized I have no wipers. I look at the box of parts I got from the guy i bought the truck from there are two arms but one of them is missing little arm the holds the actual wiper blade. can anybody send me a picture or something and recomend a electric wiper motor.. thanks in advance
