Hi All, Grant here from Wisconsin. My wipers on my 59 (vac) work well, BUT... when driving on the road in the rain, wipers running, the left wiper arm goes way too far to the left, nearly leaving the curved portion of the glass. They return to park well, and the right wiper, as it reaches it's full movement right, stops at a verticle position, (12 o'clock). This concerns me, as my original windshield was badly gouged at the left side, from the wiper arm going too far left. I don't want this to repeat on my newer glass. Any help? Grant.
