Wiper Arm Issue--Passenger Side Sticks

[tferbend]

I have a 1966 Chevy Stepside.
I have installed NEW (LMC) Wiper Arms, Wiper Blades and a Wiper Transmission Arm.

My problem is that when i drive over 35mph and my wipers are running, the passenger side wiper arm swings out too far and becomes STUCK on the edge of the window.

When i stop and push the passenger side wiper arm back over the edge, the wipers perform normally.

Any thoughts on how to correct this problem?
(would a stiffer spring on the wiper arm help?)


I'm open to suggestions...

Thanks,
