Considering Push Button Conversion...help

You'd need to find the pushbutton mechanism and cables from a '63 or '64 Dart, Valiant or Barracuda. The problem is going to be how to get it mounted in the dash, since there's no holes or tabs to retain the pushbutton mechanism. I suppose you could swap in a complete dash and instrument cluster from a '64 Barracuda. If you're planning on hacking the dash you already have, I guess you could use the pushbuttons from a B or C-body, since at that point you're going to have to design your own trim plate anyway. None are good options...

Besides just finding the right cable to replace the broken one (post a want-ad here!), a column-shift steering column from a '65 Dart or Valiant would do the job, too.
