NFAB lightbar Spacing

Hello all, i am looking at purchasing the NFAB light bar and would like to know how much clearance there is between the mounting hole and the vehicle? i cant get an answer from NFAB. i am wanting to mount 4 of these HIDs, according the the manufacture the distance between the mounting stud and the back of the housing is 4.7 inches. so i need that much space out of the light bar. if anyone has any insight it would be greatly appreciate before i order anything that may not fit.
Thanks

Anyone??

 

So you want to know the distance from the hole to the grill? I will try to remember to measure when I get home. I have slimlites on mine and I would guess there is 2 to 2-1/2" clearance at most

 

That would be great thank you. if its only 2.5" though i will have to have it modified or have a custom one made up. i need 5" between the vehicle and the mounting hole.

 

2-1/2 from back of slimlite. I forgot to measure and I am in OK without tape until Sunday

 

hope this helps, this is my setup.
