Hey Don,
I think I can shed a little light on your trouble. Lets break it up into 3 possible areas, mechanical Switch in column, The electrical switch located near firewall moved by rod from key sw., lastly any wiring issue after the electrical sw.
Start at the electrical switch on exterior of column by using 5/16 wrench to loosen 2 screws holding in place. You remove rod from key sw. and test if it now moves easy and clean. Replace key sw if rough or replace elect sw if it is rough and there is an 1/8 hole in sw. and column to put drill bit in to align new sw in position. If they check out it might be a hanging starter or starter solenoid but that is easy to test too.
If key sw is bad pay attention to disassembly of wheel and parts to get to it for replacement and note what hole the lever and star wheel were in before taking it apart so you do not have to start from scratch. It is pretty easy all in all. Jeff c
