headlight assembly has a little clips for mounting...so just get a another light and should mount up. i'd hit up a scrapyard or one of the dismantlers on here.
nice steel aftermarket bumper + headlight + headlight finisher trim subtracted from ins. check = all better with $ left to get a dehydrator for the next time

 

Been trying to contact a few dismantlers on here via PM but no responses so far I'll throw a thread in the wanted section I suppose. I see where it mounts up to the top of the frame but where does it mount to the bottom all I have is the oem bumper at this point I don't see where it would attach.

 

iirc, light has a stab in fitting on the bottom.
i meant use the money meant for pricey oem replacement bumper for an aftermarket steel bumper. that way, next time you savagely slaughter wildlife, hopefully it won't look like you have a turd hanging off the front of your truck.

 

if you are not sure, take off the other and have a peek
