Vintage A/C is offering electronically controlled a/c for cars - even with factory a/c. Their controls are now backlit. No cables, so you can put the controller where ever you want. Being al electric, I'd imagine you could design your
own face plate and adapt their stuff pretty easily? I haven't looked at their website in awhile. Maybe they would even work with you? A few years ago I asked about a "67 B Body, and they told me to contact them, that they would work with me.
Maybe they can help you out. Don't know how you can "change" from a cable operated system to something different, unless you have a control panel in mind from a cable operated system, and get custom cables made, though.
It seems to be one or the other - cable or electronic. I could be vey wrong, though. Maybe they offer servos that mount to your cable driven box?
