BAD MECHANICS - Thermostat and Radiator Fan Blade

Did you take a picture out of one of your earlier posts? I swear there was a photo showing what looked to be the kickdown linkage sloping down at a very unusual angle, thereby prompting the responses to get it looked at. It was there, it just didn't look right.
Nobody was kicking you, they were responding to what looked like a problematic situation and hoping to prevent you from unnecessary repair costs.
Post #5 and 20 had a good enough pictures to at least see that i did have the kickdown rod istalled on the carb.
Now, the remaining issue to resolve is the proper adjustment.

But, as a rookie, I have obviously been missing a few things.
Just because I have not jumped, and posted an update after every suggestion ya'll have made, does not mean that I blew them off!
The transmission seemed to be shifting just fine to me; although I'm gentle on her.
And, I did drive her from upper Iowa to OKCity after I bought.

From all the posts I have seen on several forums, it may take some trial and error to get it right, if it isn't right.
The one "no no" I had seen was in the video link that I linked several posts back is.....that the bolt/nut should probably NOT BE at either extreme end of the slider (forward or backwards toward the transmission). And there is supposed to be some adjustment on that slider built in by twisting the slider on the cable threads.
Will work that one over when I pick up the Cuda in several days.
But, even the picture of the video link in post #66, the guy is showing his 67 Coronet with the bolt at the far rear of the slider arm.
My guess is, that evey application is a little different, and parts like the lever arms of the linkage can be accidentally bent over time to effect the visual picture one sees of the tightening bolt's position on the slider arm.
