So I finally got my stuff together and sorted this question out. I learned some stuff along the way. Maybe others would benefit. Attached the utube link that got me to the final solution. The base of the problem is I did not know what to look for and what I had in my column.
1962 C10 turn signal switching and mechanism is different then the later 60's version. 62 has mechanical mechanism in the column collar. The wiring and switch is on the lower end of the column just prior to going through the firewall. I knew that but could not figure how the mechanical setup connected and activated to move the switch mech. Diagrams in the shop manual and in the catalogs were not real helpful.
So once I found this tutorial on utube, I inventoried and made the connections. Turns out I had more parts than I realized. I did need to buy the innards
Alls well that ends well (11 yrs later).https://www.youtube.com/watch?v=xZvJb1Ii8Dc
