Gauges the same 69-70?

[cboss70]

I have a 70gauge cluster with the deluxe woodgrain but my car should have standard interior. I know the bezels are different between 69 and 70 deluxe and standard. Is there a difference between the actual 69 and 70 gauges themselves? Are they all either stamped or printed with a date code?  I have not pulled the panel out yet and just want to make sure I can validate it's a correct 70-gauge set-up so I can still use the one in there and just put the standard bezel back on. (it's an odd ball a non-tach car). Thanks for your insight.

One easy way to check is go to bat and search 1969 and then 1970 mustang and look at the boss 429s for deluxe for an example. The 69 tach dash does not have the white lettering you see on the 70 below the tach.
