Retrofit help

Does anyone know what the ring measures on the outer part of the shroud in this this headlight? I’m looking to put a halo ring over the outer most part of the shroud and need to know the measurement.

 

I can't tell which shroud it is from that picture. This link has a list of shrouds and it has their measurements.

^^ also when you figure out which shroud, lower right had corner of TRS's site has the recommended halo sizes for the the shroud under the "tech specs." I can't quite tell from the pic what projectors you have or shrouds (possibly Gatling Gun 1.0 or Mini Gatling Gun???). Might have to open and measure.
