Backup Lights with Datsun Tranny?

Have any of you Datsun-trannied folks done anything
about the lack of backup lights? I've got the correct
wires isolated, but don't have any great ideas about
where to mount a switch. (I believe I had to remove
the switch on the Datsun tranny for clearance in the
tunnel.) I'm thinking about co-opting the Emergency
Flasher (hey Girlie, watch this!) switch since I don't
ever remember using it. Or maybe mounting a toggle
in the console.

Ideas?
