Gentex Mounting brackets

I just got some devices the other day, which are basically Secutron branded Gentex commanders. They didn’t come with mounting brackets I and want to know if there is any big difference between the brackets for commander 2’s and 3’s…or can they be used on both devices? I may be able to get a commander 3 bracket, but I want to say these may be rebranded versions of the 2.

The brackets are identical.

Good luck!
