Ok, so I had tried that and there is one other adjustment that has to be done first- I'm sure you'll all think I'm an idiot for screwing this up in the first place, but the little arm off the wiper motor is at roughly 4 o'clock, that had to be reset to about 2 o'clock so that it formed a straight line with the attaching arm- that ='s maximum distance of the wiper movement downwards, then I followed your suggestion and everything is perfect- well....
But anyhow for anyone who has the problem with the wipers moving below the lower window gasket and chrome and then coming to rest on the windshield, aligning that little arm with the big one fixed the issue.
Thanks
