Boy I hate to ask this question..........what is the spring loaded foot lever that is just above the dimmer switch?
Isn't that the windshield washer control? It was on my '68.
Thats what I was hoping, cause when I stepped on it....the wipers moved!!! Weird, why there? When there is a switch within hands reach????

Why is it there ?
Because way back when, someone figured out that a person's left foot didn't have any function in operating a car. Soooooooo............................they thoughtfully placed the dimmer switch and intermittant wiper control down there so your left foot would have something to do. Which freed up a person's hands to keep them on the wheel, where they need to be with 75% of drivers on the road. Now there's so much
mounted on the steering column, it litterally takes a genius to figure it all out. 
remember when the starter button used to next to the gas pedal .......![]()
I haven't located a rebuild kit for it but I haven't searched hard for one either .... good luck ... 67GTFB
