Please correct me if i'm wrong ,
but for module easy mount ,
the total wide do not have to be a bit less than 38,1 mm (single module )
and 76,2 mm (double module) keeping attention for the screw holes that have to be in the center / middle of 38,1 mm ?
(as i seen something like 37,9 mm , 37,8 mm around and also here in some "Jeff" (Capi) thread )
thanks
