OK, AC guys, I have a question concerning my installation of a factory AC into my non-AC '68 Skylark. I dog-robbed everything, I think, and what I haven't gotten yet can be got, since the '69 Skylark "dogrobbee" isn't gone yet. Simple question- I'm looking at the heater control flap and there seems to be a lot of slop in the mechanism. Looking at the pic provided, can anyone tell me if there is a bushing (say, nylon) that goes between the actuator shaft and the lever? There is a lot of clearance there, which leads me to believe that there was a bushing at one time. The box has been apart before, as it is missing a bunch of screws, and was sealed with some concrete like stuff (which has all been scraped off already)...and the heater core has obviously been replaced before, since it has no external evidence of corrosion and flows well. The pic isn't all that informative, but if you look at the center arc, the pin goes into a variable slot, and is loose. I don't think it should be. Any insight on this? I can machine a bushing if it comes to that. Thanks in advance for any info.
