The purpose of this post is to answer the following question posed by Al.
One question; is there a bushing at the pivot point for the actual cowl vent, my holes seem very large - maybe they are just worn big time. Thanks, Al
Here are two photos of the bolt assembly that I put thru the main pivot point of the mechanism. The first photo shows the main pivot point bolt with washers and nut etc. I can't recall if the main hole is oversize, but I think it is because you can use this nut and bolt to adjust the movement and tighness of the cowl vent.I don't recall if there were thin brass washers used in the OEM assembly, but I used them as I didn't want any steel rubbing on steel. Plus, I can't recall if the bolt had a shoulder on it or not. However, the nut and bolt is assembled very tight and does not move when the cowl vent handle is moved to the open or closed position. If you click on the photo you will see that the nut and bolt assembly is as follows from L to Right. Bolt head, thin brass washer,lower vent arm, thin brass washer,upper vent arm, thin brass washer, lower vent arm, thin brass washer, small fender washer, flat washer,lock washer, nut. As I write this, I am thinking more and more that all those brass washers are not needed and probably are not OEM. But, it's been working fine since 1988. Hope this helps.
