Just found the answer to question #1. I just had my hands on a Primary Rod marked 37J from a 7045193. Since the 9C calls for a 7043537 and the rod is marked 37J(which falls inline 7043536 = 36J & 7043538 = 38J) I feel pretty good about this one.
While question #4 asks about the Auxiliary Rod and this one is marked 35B. If we assumed it is the original that would be a 17052814?
No way to know for sure, but this carburetor was not a reman and it looks fairly original to me.
Let me know if you have any evidence either way.
