The RC light bar, because it’s curved, sits hard on the middle vertical shutter rail and dips back into the shutters on the ends. So I just trimmed them. I don’t see why you couldn’t cut the last 2 out for cubes in the pic above. Blue tape is where I trimmed. Just had to trim 1 shutter. Cutting grille was a little tricky. Cut the top of the vertical stems and followed the contour of the bottom edge with a drammel then sanded. Just kept fitting it on the truck and against the light and fine tuned where needed. On the light end caps they stick up a little higher than the rest of the light so I notched out the grille on the top side for the light to sit flush with the top. Sorry for the pics being sideways. I’ll post more pics later. Any other ? Just ask.
