Hi,

The 1970 Coronet R/T standard dash and Sport Satellite share the same woodgrain pieces if I'm not mistaken. The difference being the emblem above the glove box. I'm guessing you have door trim that has it also, as does mine.
I was able to find some stuff made by REM that although not exact, it's as close as I was able to find and I actually like it. Here are a couple of pictures.
