Whelen 600/M6

[167]

I know an M6 light head will fit in the side by side double warning light bezels and stacked bezels like on the front and rear of fire apparatus. My question is:

if that bezel is already equipped with Whelen 600 series LED, what has to be done to get it to house an M6? Is it the inner mounting tabs?

Whatever it is, anyone know where they are available?
