I'm confused... are you looking for headlights for your '99? Your '99 doesn't take 4x6 headlights so you could never make that work without significant modification. It takes H4703 low beams and H4701 high beams which are both 92mm x 150mm (about 3.6" x 5.9"). I have not seen any LED units as replacements in that size like there are for many other sealed beam sizes (including the 4x6 H4651). There are several lens and bulb combinations available of which the LMC Truck housings are the most popular.

I've searched, but not found anything - so here goes. I've replaced the gears with brass ones and everything works great. BUT when the lights close, they don't exactly go down smoothly. They drop about halfway down before closing and it makes a racket. Anyone seen anything similar? The linkage seems to be in good order and the motors and gears are all good.

Yes those are the right part numbers for the housings, but the wrong bulbs.
The LMC Truck Housings use 9005 & 9006 bulbs. You'll have to replace the bulb connector on the car with 9006 or 9005 connectors for low beam and high beam respectively for the bulbs to plug into the car's wire harness.
To physically easily fit on the Firebird you'll need the straight version of the bulbs (these housing come with them). 9012/9011 bulbs are brighter than 9005/9006 bulbs and will fit the housings but you'll need to trim the bucket/holder on the car for the bulb to fit since it is right angle. You'll have to trim the bucket for LED too since they have wide heat sinks and fans at the back (also watch out for depth behind the housing).

The sockets are same or nearly same.
9011 bulb will plug into 9005 socket
9012 bulb will plug into 9006 socket
The only physical difference I remember is one of the lock tabs where it inserts into the housing is slightly different but many housings are designed to fit either without trimming. Some older housings may need a trim to the tab on the bulb, but I think the LMC Housings are fine so it should just be plug-and-play.
You won't find a kit/package with both 9011 & 9012 bulbs and they won't say they replace 9005/9006 bulbs. You'll have to buy either single or double packs of the different bulbs.
Watch out for fakes or the older ones. If it has a Blue tinted coating, it is Fake or BS Marketing. Stick with a reputable brand. The glass should be either clear or possibly an iridescent coating (although most of the current/new batch usually don't have a coating).
Fun note: Wagner bulbs are often rebranded/reboxed Philips bulbs but cheaper. I've bought some Wagner 9011 bulbs that said Philips on the bulb but where in a plain white box instead of the plastic blister pack that Philips bulbs are usually packaged. I installed them in my mother's CR-V in place of the stock 9005 bulbs without issue or modification - it just plugged in. Some speculate that Wagner bulbs are Philips factory seconds.
Here is a thread on HID Planet where someone compared a few different versions of the 9011 bulb over the years if you are interested in seeing how they've changed/improved:

Sounds like if you want the brightest version, try to find a Vosla or a Korean-Made Osram (Sylvania). Either way any 9011/9012 bulb will be brighter than any 9005/9006 bulb.

You were definitively on to something. Disconnected everything and measured ground on all leads, checked out ok. However, noticed some moisture damage in both connectors, ended up splicing in new ones on both sides and everything works great now 😎

Has anyone just hard wired the two connections for the headlights? I not only had corrosion but two male ends broke off into the female end. I can find a female piece for about $30 but no male clip in stock now, I could get an entire new motor assembly with the male clip though for 99 (for 2). I'm really thinking of just getting some butt connectors with heat shrink and snipping and connecting. Sorry if it's already on here I read 3 pages but not 102.

You can certainly do that. The connectors are really just there for ease of assembly and repair. If you crimp them use the 3M heat shrink butt splices. The plastic melts and liquefies to make a water-tight seal around the bare wire. https://www.3m.com/3M/en_US/company-...8731280&rt=rud
I appreciate the help!
