I'm curious if they would part with the blueprint. Would be nice to know the exact dimensions and angles for the brackets, so we don't have to reinvent the wheel. For the bar you could do whatever you wanted. I was thinking an extruded aluminum bar that you could mount lights in the t-slots.
I'm curious the same. There used to be a simple bar mount that I can't find anywhere anymore. So, I'm the same as you, looking for a way to mount the lights on the bumper.
