Yes. If you look up MossMotors in any dictionary, you will see gold. Sad, but that’s what the market will bear for restoration parts for original TDs. Aren’t you glad you have a reproduction?
I’ve seen excellent results on dashes where the owner simply cut a glove box door out…CAREFULLY…and hinged the cut out piece.
I’d think you could reuse the old mount holes and mount the wood dash with finishing screws. I know this will be obvious, but make sure you check whatever screws you are using in the old mount holes before you drill the dash.
Yes, you will want to attach a firmer mounting block to the back of he dash, to which you will attach the steerign column. An inch or so of dash thickness is not enough to firmly support the column.
Hard to tell without seeing what you need to do to detach the wiring. On my Duchess, all the wiring to the switches and gauges attach with quick connects. So I am able to unplug the wiring without cutting anything. Whether yours is the same or you have to cut the wires, make a detailed schematic as you go, so you can wire up the new dash easill.
