1970 Duster dashes

I think I know what you're talking about. The 1969 Valiant had a square surround for the fuel, amp, and temp gauges. The main body of the cluster was textured black. I owned a '70 Duster that had the left-over '69 Valiant cluster. I also owned a '70 Gold Duster that had the conventional wood-grain cluster with round gauges for fuel/amp/temp. My best guess is that some early 1970 Dusters got the left-over '69 Valiant clusters with the black facing and square gauges, while others (later?) versions got the wood-grain with round gauges cluster. Too many years ago, didn't take pics, but hope this helps.
