Marcos Maniacs

The overdrive switch location seems a tad strange and an afterthought. I
wonder if the essex equipped Fords, TVR's etc. had the switch there also?
What I am planning is to use the same setup on the steering column behind
the headlight lever switch that the Triumphs used - which is basically a
long additional lever behind the headlight switch that would engage the
overdrive.  Since the Marcos used the exact same headlight and blinker
stalks anyway, I'm not sure why they just didn't add the overdrive stalk
there instead. In my opinion, it's a bit easier in the fact that you don't
really have to take your hand off the wheel to engage it, and it seems more
elegant. The only possible reason so far that I see why this wouldn't work
is that the overdrive stalk could possible obstruct a portion of the vision
of the tach or speedo - which it doesn't on the Triumphs.
