If you dont mind getting rid of the woodgrain you could get a later model radio bezel. Thats what I did in my Monte Carlo. It bolts right up using the same four screws and looks a lot cleaner, plus Scosche makes a mounting kit for it.

You could get it here,

But I found mine on ebay for 15 bucks shipped... NOS.

Heres the dash kit I used. On the 78-88 Elcos and Montes the radio bezels are interchangeable so this will work for you as well.
