I installed a caddy tilt and tele column in my 69 c-10 quite a few years ago,I dont really remember what year the column was,but it was simple to put in.the turn signal plug was different,but the color code on the wires was the same so I put individual connectors on each wire.I dont think I used the ignition switch on the column.I had a car 4 speed in my truck,and I am pretty sure my caddy column was for a floor shift,so it didnt have a shift lever on it.this was quite a few years ago,my memory is a little fuzzy.
