Unfortunately I don't have more photos showing how I mounted the projectors to the housings

, but to give you an idea...I sat the projector in the headlight housing from the back and made sure it was centered. Use the bolt holes to mark the locations to drill the holes.
A few things you should consider...
Everything needs to be solid, but you also need room to adjust things. You need to be able to adjust the projector horizontally, vertically, and rotationally (due to the straight cutoff).
*It is important to get the projector mostly aimed in the mounting process, then you can use the OE adjustments of the headlights for fine tuning.
You also need to address clearance of the retrofit for re-install into the truck. Lucky for us, we have a ton of room in the engine compartment.
Here are the pics of the brackets that hold the headlight housing to the radiator support-
Then you can mount the bracket (without headlight housing) to the radiator support and use it for reference to trim the support.-
Trimmed-
That's it for now... I will try to finish this thread up soon

Just ask if anything needs to be any clarified.
