I replaced the driver's side LCA in 108-degree (that's 42 C for folks with more sane units of measurement). Heat index was 114 and I had limited shade. That was a huge mistake, but I took breaks and drank six bottles of water. My shirt became so heavy with sweat that it was like some kind of weighted workout jacket. Oh, and to top it off, we had a brief downpour in that 108 degrees while still in full sun. It was surreal. By the time I went back out it was a literal wet sauna. Man, everything hurts today and I had all kinds of crazy dreams waking me up last night so I didn't get a good night's sleep. Don't do this. Don't be me.
The key to successful installation *for me* was jacking up that knuckle to get the LCA completely horizontal. That allowed me to start the front bushing and the rear bracket+bolts with ease. DD, I've checked my other, new LCA and the original, removed LCA and the bolt hole on that rear bushing (or whatever it is) is boringly perpendicular to the rest of the part. So I'm not surprised that it was easy to install in my case. Now, I don't have OEM replacement parts, but some (NOS?) Beck Arnley ones, and they may be different from other brands.
My biggest problem with elevating that knuckle (which was a *requirement* for me) was that the floor jack was occupying the space where the ball joint needed to be when I'd swing the LCA up to get it horizontal. I tried turning the wheel all the way to the left or right to try and make some space, but in one of those directions, the end link contacted another piece of the suspension when I elevated the knuckle so that was a no-go.

I ended up returning the steering wheel to center and went another route: Moving the knuckle fore and aft. In the end, I moved the knuckle forward a little farther than I wanted to as shown below. Hopefully I didn't hurt anything. After hours in the sun and an immobilized vehicle in my apartment parking lot, I honestly didn't care as long as I could get it moving to take it to a shop if needed. The other challenge was my not wanting to remove the cap from the ball joint boot until the very last minute. There are a lot of sharp parts down there including the knife-like disc brake shield, and I didn't want to destroy the ball joint boot.
DD, this is where I would say that removing the brake assembly, hub, and shield might help. If it allows more jacking options or keeps that ball joint boot safe it is well worth the additional minutes and bungee cord required. I will definitely do that for the other side. Also, if you're filming it like the guy in the video, it's a lot better for the viewer.

Speaking of the video, I think the guy got the torque for the pinch bolt wrong (too high), and I can see from the service manual how he could have done that. I'll confirm that and if so, drop him a note in his Comment section.

Found out what was making the noise after I removed my wheel

(yes, it was there, but it wasn't making the noises):

Captured the order of the three different bolts for that rear bracket (actual LCA bolt would go in the empty space among them):
