I'm thinking mine are getting around 120/130 as well.
Is starting position towards drivers side or passenger side?
I have a 2A but it has a 3A windshield so I figured it more appropriate to post here.
After looking at the size of the arms and blades I had the wrong ones too as I've seen the 3A windshields blades are 9" - just not sure if my arms are wrong too - I'll have to look for a model number or something on them.
CJTHREEA, I don't know the actual range of motion, but 120-130� is about all you want.
Assuming they are positioned in the stock location, when 'parked' at 0�, the top of the wiper comes pretty close to the edge of the windshield when reaching the degrees mentioned above.
I can measure the angle tonight if you want it, but my motors are SF-616...The standard issue for the CJ3A.
