The ididit unit is nice, but way too mucho deniro for me!
All the 70's Mopar tilt coulmns were GM made (Delco division?). I have a couple, but cannot access them (700 miles away in storage at a friend's). I recall everything was different and the switches had special wiring adapters (like what you get from Crutchfield when you buy an aftermarket stereo). Mine all had normal Mopar keys, but I don't recall the orientation.
71/72 Chargers had tilt-columns as an option, but only available as automatic on the column cars!
