I am looking at the wiper door mechanism, but yet I visualize my flapper setup as being different, being a ragtop I sealed off that flap years ago, and removed the lower door entirely....
AS I RECALL, I think I renewed the rubber over a center metal factory riveted sandwich,.....bolted it together again, it worked fine but was always on recirc all the time anyway,.....
so if there is anything usable you are welcome to it, but I have to go check/see what I can to seal it off right for me....maybe too much work at this point...:smash::thumbs:
