shouldn't for this as long as it's a simple case of back / forward allignment, the slam is bolted on at each side above the headlights, the bolt holes are enlarged so allows you a little wiggle room, just loosen them off - pull / push the direction you want it, nip up bolts while holding and see how it looks. as i say it may be a case of left out and right in a little to get it sat evenly but i'm sure you'll see when you do it.
