The swicth that goes on the column has a square box at the bottom and a great big toggle lever out of the top. I have a pair on my '53 88 that I could take a picture of for you if someone else doesn't post one. I did see a NOS one listed on Ebay a while back for $250.

I'd like to get that feature working on my 88. I doubt my switches are any good. I may have to open one up and see what kind of engineering a guy could do to rebuild it. I have three cylinders. One good one and two that need rewired.
