Hey Kurt, thank you SO much for checking in... Just wanna make sure things are good. I thought I had the pitman arm pictures in here somewhere but maybe not. Here is what I have in my picture file.
What makes you think the carb is original? Is this the norm being dated 4 months away from most everything else on the car? You got many other documented '68 original cars with this early carb dating?
I am not Kurt, but I thought I had posted a while back and said that I thought your carb was probably original but Kurt would have a better idea for sure. That big of a gap is not the norm, but you have so many other original components it would be hard for me to believe it is not original. Production on Z28s was ramping around that time the carb was assembled so it could have gotten shuffled back not used right away.
Let me check on the pitman arm.
