70 Duster correct instrument bezel

[mrhinsjc]

In my stash of parts are two instrument clusters. one is the standard non-rallye wood grain piece. The other is one i had never seen before- it is a black ribbed unit (ribs run vertically). I was
told by my mopar guru friend the black ribbed unit is correct for a 1970. Can any of you people shed any light on this? Thanks.

You can see the 1970 Valiant, Duster & Duster 340 clusters at https://www.hamtramck-historical.co...ershipDataBook/1970/70_Valiant_Duster0017.jpg

Vertical ribs sounds more like the standard version in a 1970 Challenger, can you post a photo?
