First off, the panel is FUBAR. To get another, you will have to find it in a junk yard. Try to get one that does not have the woodgrain separated from the base. It is heat welded, and a RPITA to reattach. If the base is the wrong color, you can tape off the chrome and woodgrain and get some SEM 4565 and paint to match.
I have contemplated an aluminum panel to replace the woodgrain front. I would "engine turn" the surface, then cut the openings. I would also have it powdercoated with satin black to minimalize it.
Another option is to use the dash from a 91-93 RMW. It will fit, but the woodgrain has a little different color and is glossy. The map pocket would fit over the "Roadmaster" on the donor piece. You can also spray a dull coat over the woodgrain to take the sheen away. It is a temporary fix, until you find an original piece.
You probably need the original radio mount to replace the rigged one you have.
