My old '79 column had a cruise control stalk which only consisted of a button on the end to activate the cruise control function.
Kevin, you don't see many of that type around like you posted.
Jack the 78/79 did just have the button on the end for cruise...slightly different than newer ones...a bit of a carry over from the mid 70's I think...
This is one I sold a little while back...
Those and the 80/81 are getting hard to find....
