I've been working on the HUD install on my 99 Coupe - good news was that the cluster was HUD enabled - just plug and play.
Bad news:
1. I don't have the columns for the tabs - I'll need to drill. Now if I cna only find a drill with a right angle attachment, or a 3 inch drill and bit (there's 3 inch clearance between the place you're supposed to drill and the windshield)
2. The wire harness I bough from Josh doesn't work with my cluster - the side that plugs into the cluster is the wrong size. Luckily the used parts I bough on e-bay included the wire from the swicth to the cluster.
(I'm starting to think it's included with the switch if you buy it from the GM parts store / Fred Beans)
3. Upon opening the windshield heater grate - there's the security LED on the right, and "supposedly" another sensor on the left - my car doesn't have anything on the left Either it went missing the last time someone opened up the car, or the 99 coupe didn't come with one - anyone have any ideas what the sensor on the left side of the grate is?
The sensor on the left is for the Twilight Sentinel. You can buy the sensor from GM for about $12 and add the option, provided you can find someone (or a dealer) with a Tech 2 to turn it on for you. That is what I did while I was adding HUD to my 99.
I found an article that said it was a solar sensor. Once I heard that I was less concerned - we don't get too much sunshine in Seattle. Though I think I'll take your advice and do the twilight sentinel upgrade / reprogram.
Though in Seattle it'll be called an Overcast Sentinel
It has been suggested that you use rubber expansion nuts. I actually bought these but ended up not using them because the bolts were already there in my 04 coupe. Home Depot doesn't sell them but I was able to find them at Lowes. They are also called "well nuts". You screw into them, and they expand outward for a snug fit, kind of like drywall inserts.

I'm familiar with well nuts. They do a good job in certain applications. I guess what I was wondering about it that if you use them, then the projector doesn't sit down flush against the panel where you drilled the holes. The well nuts have a flange on top and the projector then has to sit on top of this flange. I didn't know if this would raise the projector up enough to cause any alignment issues with the dash bezel, or any focus issues. Even though I have a late '99, I doubt I would be lucky enough to have the factory studs already installed. I prefer to have all the parts necessary on hand and not to have to be stopping and running to the auto parts, etc in the middle of a job.
I totally understand. I bought everything from the well nuts to the Dremel right angle attachment BEFORE beginning. Unfortunately, that did not stop me from having to drive to Home Depot with no dash or console I had to go find nuts for those bolts that were already there. And believe it or not, I am such a dumbass that it took me three separate trips into the store to figure out which nut was correct. Only a dumbass like me would assume that an American-built Corvette would use english size screws
And when the hazard switch is disconnected, you have no turn signals so you gotta use your hands! My feeling is that the little flange wouldn't hurt the focus that much, but just my 0.02.
After drilling the holes, what method did you use to fasten the projector down? Is the panel that you drilled into metal or plastic?
I used rubber expansion nuts. Bought them at Ace Hardware (Home Depot didn't carry them). The thickness of the expansion nut flange is so minute, it has no bearing on how the projector sits in the projector cut out. The material I drilled into was plastic or maybe fiberglass. Definately NOT metal. The plastic is fairly soft, so be careful not to make the holes too big. Take your time and move slowly. Good luck w/ your project.
