I would rather hang around for a later model W124 to surface. The 93's around here have the wooden strip across the whole dash - probably what you're looking for.

It now would be a straight swop. All ancilleries / plumbing / mounting points, etc. will be the same ...

gotta lot of time on your hands, hey ?

You should be able to find this item at a breakers yard for a lot less trouble (and maybe even less $$$) than on E-bay ...

Good luck !!
come to think of it, you will probably want to change the door trim now as well to fit in with the wooden inlays on the dash ......
