Just a tip dude, do a search, theres already like a million posts on this already.
Quick summery, flat front = quad light compatible, slanty = not quadlight compatible
if you want to run quads on a slanty front you'll have 2 do some decent mods to the brackets, mouting points on the car, or change the whole rad support 2 a flat front item
gaurds, beaver panel and bonnet also have 2 b flat front aswell
