Hi, I am new to the forum, but am also replacing my radio. I'm going to try to a CD faceplate using the radio one as a template for my 91 LS400.
I found great instructions on removing the radio/AC unit, and a place that will repair any part of it very reasonably. They have provided the info with the idea that you'll send yours in to be reapaired, but perhaps you can just remove the old player and install a new one in its place.

Lots of luck,
