The fitment differences between the JDM vs USDM front end is the headlights are larger and the hood is longer and taller... So if u use a JDM bumper, you have to get a JDM hood, and JDM head lights... But before the hood will fit right and fully latch, you also have to get a JDM radiator support (only some of them work right, forgot off hand which ones) or u can modify your radiator support to work see here: http://www.jdmuniverse.com/forums/sh...ad.php?t=17535
