I installed the wiper drive assembly today and ot feels like the passenger side shaft plate doesnt aligh properly. That is, like it doesnt want to mate up to the inner surface of the cowl. With a little persuasion I can force it up against the cowl and get the bolts in but then the link feels stiff. I checked the parts book for a 72 3sp/variable and I believe they are the correct parts but there is some variation based on actual date of manufacture. How accurate are the manual illustrations? They show the transfer link to be canted or bent. Mine is straight. The drive link looks different from mine also. Any chance the donor cowl from the Challenger was different?
