We have the ones that Gary sells. Love them. Had them in our last GMC also. We have a 78 Royale. So I made our valance out of solid walnut. Used 3/4 X 4 X 34" on the walls. Then another piece of walnut on the face. 3/8 X 3 X 34". To get the 3/4 piece to match the curve of the walls. I placed the board against the door jam. Then traced the wall curve. Want some photos. Let me know. Bob Dunahugh
