LCA bushings, SPC UCA setting, or something else? (1 Viewer)

Good video for use of the SPC press tool here: Specialty Products Company | SPC Alignment | The Automotive Alignment Leaders - https://www.spcalignment.com/component/spc/?task=part_description&pid=40915&region=USA&make=Toyota&model=Land%20Cruiser&year=2016%20-%202016&from=USAFrom&to=USATo

Update: I've been swamped with stuff and the truck needed to go back to the shop to have the diff fluid changed on Friday as I just finished the gear break-in, so I had them look at the cam bolts as well. They hit the bolts with some kroil and let it sit and he called me last night to say the bolts came free easily. Bushings look fine. He's going to liberally coat with anti-seize, adjust the UCA ball joint from +2 to +1 caster, roughly set camber with it, and then have it aligned for me. I'm guessing the failure to adjust towards the ends of the cams was because of the UCA setting (which had aggressive caster and highly negative camber set) and/or an inexperienced tech.

Anyone need a brand new set of LCAs and/or SPC cam bolts? If not I'm planning to return them tomorrow afternoon once I pick up the truck.

Went for an alignment yesterday and they got the driver side caster to 3.9* but the passenger side LCA cam bolt was frozen and just turning the bushing so they had to take the driver back to match. It has a pretty decent amount of what I would call "bump steer" and did so even when it was completely stock suspension, tires, wheels. My rig did have 3 winters on it in Wisconsin before I got it in 10/21 so thats likely where the seized bolt and corrosion came from. Not really trying to pay a ton to get it perfect, but 2.5* caster kinda sucks.

Anyone else go thru this like @linuxgod ? I might give Slee a call and see what they suggest. Here is what the sheet looked like 3 months ago and now when I went back for better:

Cut the cam bolt out and replace it. The replacement bolt is cheap. Figure two hours of labor.
