Looking for a 70-71 E-body Wiper Crank Arm w/ pin - Part number 2822289
This is the crank arm for 3-speed wipers. Same one is used on 71 B-body models.
The "squared" off mounting hole that attaches crank arm to the wiper motor must be in excellent condition.
[already have one where the hole is deformed]
The crank arms have 3 flat sides and one rounded side to key them to the crank ao they can only go on one way. I have seen them incorrrectly installed with a big enough wrench
