Ralley dash in a convertible?

I have a ralley dash out if a 68 barracuda that I had planned on redoing and putting in my convertible. It wasn't until know that I realized there wouldn't be the space for the top switch since the bezel covers the whole action on the dash ( in comparison to the regular dash of a 69 dart ). Did they put ralley dashe in convertibles? If so, were te different from regular ones r was the switch located elsewhere?

Thanks guys!
