help guys, started my retro today with 2.5" FXR's and i trimmed the housing as close to powerz write up as i could, fit the projector in and from the mounting holes to the back of the housing i have about 5/16"-3/8", looking at lifted5.4's thread i noticed his is about that, so the mounting holes aren't going to sit directly onto the housing? i don't want to trim too much
