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.
