I'm doing this too but I'm adding the cruise control along with it.
Stalks, pre-made wires to go from the stalks to the back of the clocks (they're on eBay), and then just have someone to enable it. That's it.
But I want the dot-matrix clocks, so I'll be getting those too along with mileage matching to make sure they're the same. That might be something to look into if you haven't already got them
