ok here it is. i have to buy WINDSHIELD WIPERS TRANSMISSION/LINKAGE. well i found one and i would of bought it but, the person on the phone asked me if my wiper motor was Square or was it round. ummmmm ok since i have no clue what to look for im stuck. he says there are 2 styles for the car. so my ????? is what style wiper motor was in a 1964 chevelle. and well i have a set for a 64 impala and the bars are round rods. the one that is out of the chevelle is flat stock styles. so any help would be super.
