They are from Midwest Creations. Look them up in the vendor section. Jeff has been around for years now and has sold quite a few.
the alignment seems great out of the box. I don’t have a good flat area to park in front of a wall to do the measurements. For now they are fine
I'm guessing they have a jig that they use to CLOCK the retrofit projectors to each other, but doubtful that they worry about vehicle height as that's going to be specific depending on the suspension setup. They may be fine to you, but projectors, if not aimed correctly, can be nasty to oncoming traffic, hence the sharp cutoff, and where the lower cutoff needs to be per DOT standards. Pretty easy to run to a local parking lot with a wall to get it right. You have done the right thing by doing HID's in a projector retrofit instead of just slapping them into a reflector housing, but getting them aimed properly is part of the deal as well, for other's benefit more so than the driver.
I do know Midwest though, I've researched them plenty when I was debating whether to start retrofitting myself or pay someone to do it.
Today I went back to the local Pick n Pull after I found out that my armrest wasn't functioning properly. I took it apart to find the locking mechanism was frozen in place. When I went back, the Golf I had pulled the cupholder console from the other day still had the armrest that I removed, sitting in the back seat. It was functional so I snagged it! While looking at the car I thought to myself, I should grab the parking brake handle too since they are specific to that center console (angled a bit more towards the driver seat). So I got that too.
Went home and re-installed everything (I had bent my other parking brake into place so it was fine, but figured why not get the one made for the console for cheap). I now have a functioning armrest, and a cupholder center console, with a rear slider single cupholder. Pretty stoked, have been looking for a couple years now.
