I have a set of 4 cibie oscar replicas/copies brand as SIM 3205.
Dimension wise they apper the same as cibie oscars.
I just tried to mount them onto a works style bar and found that either the lamps are too deep (they are 115mm deep, 55mm deep from the mounting bolt to the back) or the bar doesn't fit far enough forward.
The space for the outer lamps is basically nothing, at the moment i would just be able to fit a slim line wipac
