S&W lightbar lens questions.

[Kaotik_Kustoms]

I'm kinda new to vintage lightbars. I have a S&W model 8887. An acquaintance has a model 80. Our question is: Are the lenses interchangeable?

I'm not 100% on this but I think the different numbers had different options installed.
I have only worked on one of these in my lifetime.. I think the domes can be swapped.. but the domes may have cutouts for options you may not have.
