Thread and dimensions of M38A1 Wiper Arm Nuts?
Posted: Tue May 28, 2013 1:21 pm
Can anyone tell the thread and the dimensions of M38A1 wiper arm nuts? Or better yet, does anyone have a pair that they don't need? My Jeep was missing everything and these are the last parts that I need to complete the windshield wiper system. (I still have to turn the motor shafts down to size and thread them. That's why I need the thread size.)
