Different Fabrication Techniques and Tools

Binger, I applaud your project, but I feel there are better fabrication tools and techniques that could have been used.

You could've cut them apart with the technique I note below. Then you could've left the OE lens intact.

If you do this yourself use a fresh blade for the second lens. My blade was pretty dull after the first one and it actualy snagged and shattered the lens as I was cutting. Its still a tight fit but it has a bit of a gap...but that will be covered up later.
You already know that a keyhole saw can shatter the plastic, but you may not know that grinding stones aren't good for plastic, as they load up with melted plastic, get jittery, and don't work well for non-metals. The best tools for the job would have been a hole saw for the ends of the oval and a fine hacksaw blade in a open-end handle. Barring that, a Dremel with a #199 bit works well this type of plastic (for both curved and straight cuts).

They make cosmetic mounting gaskets for these housings that I will eventualy put over this gap.
They have no mounting points since (as you say) they are mounted in gaskets. The gaskets will not go "over" the gap -- they fit over a flange, so you will need to resize and reshape the gap to fit the gasket, then push the lights in. The manufacturer should have a template for the hole.

Good luck!
