[Ess]

While not about lightbars or lighting, I am hopping someone might still be able to help me

I am looking a creating a 3d model of the Setina pb100 for a personal and was wondering if anyone has and spec sheets or reasourses that can assist in the creation of it.
Primarily the diffrences between the 12"/16" and how the PB-5 wrap mounts to the pushbar
