I'm trying to align the wipers on a '91 cab but I only have the arms from my '98. Is it possible to change the starting location in the rotation cycle, rotate the nobs on the cab? The notches on my '98s wiper arms are too much toward the 12 o' clock position so the wipers rest in the middle of my windshield and cycle past the A pillar. I'm wondering if '91 arms have the alignment notch in the a different spot.

I upgraded my 88-94 arms to the 98 style, it was a direct swap, nothing was different other than the design of the arm and wiper blade attachment fitting.

Remove the cowl vent and, reinstall the wipers. Then, using a 10mm socket, loosen the linkage for each blade assy and set the blade where it belongs. Then tighten up the nuts and reinstall the cowl vent.

In other words, if you shine a flashlight, right now, into the cowl vent directly above/ behind the wiper motor, you will see the adjustment nuts for each arm.
