This will be a revision to the previous post on the wipers. Turns out the boss wasn't totally happy with the way the passenger side wiper was positioned. It didn't lay horizontal like the driver side. And that was the whole reason for the mod to begin with. Truthfully I thought it looked out of balance also. So I guess criticism to failure is incentive to pursue perfection. Back to the drawing board. The only way this was going to happen would be to increase the stroke (arc) of the blades. Which meant increase the length of the wiper motor linkage. The question was though by how much. Laid down the windshield frame and disconnected the motor from the main linkage, and by moving the linkage and watching the wiper blades, 1/8" gave what was   
needed. Off to the bandsaw and cut the linkage in the middle. No turning back now. Clamped it to the welding table and used a piece of 1/8" welding rod as a spacer and tack welded it. Remounted to the motor and main linkage and turned the wipers on. Too much movement, the blades over shot the glass and there was a slight binding in the main linkage. That was when I realized that 1/8" equated to a total of 1/4" as the motor made a full circle. Took it back apart and cut 1/16" out of it and rewelded. Reassembled then removed the wiper arms and made sure the motor was in the park position. Remounted the blades in a horizontal position and turned them on. Now that was more like it. In comparison the passenger side is significant, The 
driver side not so much, but definitely more along with a total center section clear. I can see where the after market can get some bad feedback, because in our situation 1/16" made a big difference, so if you factor in slight manufacturing inconsistencies in windshield frames and motor placement there is bound to be negative outcomes. So bottom line is the end result is what the boss was looking for and we still only have $20.00 into it, and of course more time.
