Chrome projector headlight test-fitted on a dark blue Ford truck…

If the grill reinforcement has been twisted (as from unrepaired collision damage) for a while, the headlight may not sit exactly flat. So I clipped the longer top inboard mounting boss so the top outboard mount would fit.
IF THE IMAGE IS TOO SMALL, click it.

It probably would have been better to use a couple of washers slid onto the post (held by another screwed down) to make the cut closer to parallel with the original surface, because mine ended up slightly angled. I also found it necessary to trim the flange that wraps onto the top of the grill reinforcement where it touches the limiting post (to the right of my hand in the bottom right pic). Another fix (for both) would have been to simply stack a few washers behind the OUTboard mount to space it rearward into the grill reinforcement. But I wasn't sure the screw would be long enough, and the snips were handier than my box of screws & washers.

All of my trucks' lights came from this seller: black https://www.ebay.com/itm/273562204627 ; chrome https://www.ebay.com/itm/274382325575
