I have a very early Avanti serial number R1016. The wiper mechanism on the passenger side had broken out of the cowl many years ago. Looking under the dash I can see that the wiper on that side is disabled leaving the only operative wiper on the driver’s side. I intend to make this repair but want to make sure it’s right. I seem to remember a service bulletin that addressed this problem and was hoping someone here might be able to copy and post it here. I think the factory actually beefed up this area in the cowl in a similar manner that was done with the doors due to the cracking around the regulators. Anyone out there familiar with the problem, repair and proper adjustment.
