That ZROADS mounting location has milled slots so you could set it up differently. I like the way their light rack tucks into the windscreen frame. However, the lights they are using are small so that messes up the spacing.
@ResidualGenius contacted them about getting a non-drilled version so he could set it up with larger lights (I think he was kicking around 6in round lights, but I don't remember exactly). Alternatively, you could fab a new plate on top of that one and drill it out to make your light spacing work out.
The 50in lightbar from KC has 8 gravity pros on it and they are 6in, so thats probably the upper limit on how many you can run. Thats also probably what will end up on my truck whenever it gets here. I really like the way round lights look on the bronco. I think the Flex era series are probably better lights, but give me the old school round ones with Smiley covers. And also slot mags, but thats a different topic :)
