I have an original 70SS with the muncie 4 speed. I am trying to hook up the reverse lights as they were originally. Am I correct in thinking that there should be linkage from the transmission to the steering column? The arm is intact on the column, but evidently someone removed the rods and the bellcrank. I've seen this setup in the catalogs, and although they seem a little pricy for what you get, I'd like to have it work the way it's supposed to.
