Electric wiper motors the pickups was first offered for an option in 54 . Prior to that only vacuum was available. In the last 40 years I think I have had less than a 1/2 dozen off them. 1 in the last 10 years . 0 in the last 5 as most of the old yards have went away. I think they cost about $30.00 as an option in 54 which was quite a bit of money. So not a lot of trucks were offered with it.. So when you figure attrition , trucks getting crushed , etc , they hardly ever appear. Rare indeed.
