Which will fit?

I want to put a pair of lights behind my billet grill. 4WP has pro comp kits for sale now, but which ones will fit? The 5,6, or 8 inch? I want the most light i can get from there. Also, do i have to cut the stuff out from behind the grill? I looked back there and im not to sure how to make them fit. Thanks for the help.

Without cutting the original grill you can fit some PIAA 1500 driving lights in the lower opening.
Anything larger will require removing or cutting the grill. Also the bottom of the grill area in front of the rad. will not support anything much heavier than the 1500 without shaking the lights. You will need to reinforce this area to solidly mount larger lights. If you have a tranny cooler the depth of the larger lights may also be a problem.
