Check to see the actuating rod didn't fall out.
Its on the left side of column and shares screws with the ignition switch which is on top of the column. You should have a nut and a screw holding it,remove both , the stud will hold the ignition switch in position. The rest is self explanatory. If you need a pic I think I have one on a column.
If the rod popped out just push the plunger down and insert rod and your done.

Roger ,

if you have a pic that would be great. also , if I was to go to a foot activated dimmer instaed of removing switch from column which plug at bottom of column is for dimmer. Or maybe a better way to ask is what color are the wires in the plug

Why would you do that!?!?!??!?! Seems it is easier to replace the switch than to make extensions for the wiring and get the switch and then bolt it to the floor, just doesn't make much sense to me...JMO

I agree. It would cost more to Jerry rig it than to fix it right. I replaced mine yesterday after reading this post. Cost of beam selector switch was $13 from Autozone and they had it in stock. You have to remove the 2 bolts holding the column up. Then just losen the 2 on the floor/cowl panel enough so it will drop. Then you have 1 nut and one bolt. The nut is 1/4 and the bolt is 5/16. The 5/16 is in a tight spot, but a set of small starter wrenches, 1/8 turns at a time, and some patience, and it was rather easy.

added... Mine is an 81
