1969 GTX plastic instrument lense question

I have two 1969 Plastic instruments clusters which I think are for a GTX. One has on the bottom lip of the lense... Lights, Panel, Washer, Wiper. The other lense does not list these and is left blank.
Both have the Speedo MPH read out as 1,2,3...10.11.12 etc so they are not the 1968 style on the lense. Could one be for a 1969 GTX and one be for a 69 Coronet R/T? Why the difference?

Thoughts?

It's a plant and/or time of year difference/change ..... I started tracking it at one time but never saw enough of them to come to a conclusion. Are they still attached/with the cluster they came off of? What is the date on the cluster & what's the plant & SPD of your GTX?

A question that has been asked many times.
