Wow, thanks! I can't actually recall where I saw the info. It was all other people who led the way, probably on the 718 forum. I must do better at giving credit.
You can buy new inserts at Suncoast, the two switch modules and the bottom bezel.
Start here, pick your transmission, then scroll down to steering wheel trim:

Or, you can do as I did and buy used parts. I got mine from a specialist in Germany whose info eludes me. I'll try to find it and edit here.

The work is not difficult, but study up on the procedure before you start popping out the airbag. Also, you need to be the sort who is comfortable with pieces flopping loosely and threatening to fall apart at once, while you memorize the routing of the wires as you pull them free. This is where used parts help a lot, because the wires are pre-bent, so they fall right into place in the various bends and clamp points, making reassembly quick, with less jostling of other loose, flopping pieces.
Oh, here's illustrated guidance:

I did my swap without stripping the wheel down as they show. I did only the minimum necessary to place the new inserts and plug them in. BTW, every plug is unique; idiot proof.
