C1 Upper A Frame Pivot Shaft

[Jerry Clark]

I would like to know if anyone can identify the thread size on the upper A Frame pivot / cross haft. I need to jamb nut this shaft but nothing seems to fit.
As always, I appreciate the help

I know for a 1965 it is a 7/16" 20 fine thread (not a 14) and I believe it is the same for all c2's.

way larger on C1 Jim, they appear to be in the .780 range however;
I understand Corvette America, (the customers source for this part), are selling incorrect reproduction replacement shafts. The repros are threaded the same on both ends and herein lies the problem.

What thread are you after. The inner one or the outer bushing thread. The outer is .750 but is an odd pitch. I think it is 10 TPI
