Must be a 6 cyl. tach then. I already removed the circut board and can find no stampings on the tach other then some very faint inked stamped numbers or letters, can't really tell since they are so faint. Dash panel looks to be all original. Did GM use the woodgrain trim with 6 cyl. engines? Figured the woodgrain trim level would be on the upper end Cheyennes and V-8's??
