Im still holding on to my little orayer that my adj. Phb fixes it. Lol

The LCAs can change the pinion angle unintentially, however if you are trying to center the thrust angle of the rear axle you can leave one LCA and adjust the other side only. This will straighten the rear axle without adversely affecting the pinion angle.
I assume you are saying to leave one of my non adj. LCA's on the car as is and install ONLY one adj. LCA??
I do understand that this would correct the thrust angle but which side do I adjust to match?
From the fenderwell to my tire on the passenger side is 6.5 mm and the distance on the driver side is 5.5 mm. These measurements are when the LCA's are mounted in the lowest hole of the relocation brackets.
When I place the LCA's in the second lowest hole of the LCA's. The measurements are 6.5 mm on the passenger side and 6.0 mm on the drivers side.

I was told that it was my solid UCA causing this problem.. but that makes NO sense.. I think its my LCA reloc brackets.. I bought them used and they had a slight bend on one of them. I am going to replace them with a brand new set, and the adj PHB, and hopefully that will correct my problem.
I did not mean to mix and match control arms. Use adjustables on both sides, but when adjusting only change one side at a time and drive the car to see if there is an improvement. If you adjust both in the same direction that changes the pinion angle. Get that set first if possible then adjust the thrust angle to center the steering wheel.
The UCA will not make the steering wheel off by itself. With no other changes but the relocation brackets, you can assume they are causing the problem. However simply changing them will not necessarily fix the problem. The new ones can cause the same problem because they are solid pieces of metal that bolt to the axle. If anything is not perfectly straight in either the brackets, axle, or even body mounts, the alignment will be off. That is why adjustable components exist, to make adjustments perfect.
I would suggest that you start from scratch; remove the lca relocation brackets,install the stock lca's, take measurements from each lca front mounting bolt to its rear mounting bolt,( should be the same ). Install your relocation brackets & adj. lca's; adj the lca's to achieve the measurement you took above, ( use the same reference point you used above, not the lca rear mount, as most relo brackets will not maintain the correct geomerty ). Do all measuring & adjusting with weight on wheels or stands under axel housing. Good Luck
When you get your adjustable LCA's you'll be able to correct the front to rear issue. If your front to rear is off then your binding the UCR now. Adjusting the F to R will with the LCA'a will take that bind off the UPC. The adjustable UCA will allow you to change the pinion angle.After thinking about the sequence that I put all my suspension parts on, I think my steering wheel was fine, until I put my aftermarket sold UCA on.. NEVER had a steering wheel problem until after that. My adjustable PHB, and double adjustable LCA's should be here by the end of this week, and will get installed over Christmas weekend. After thinking about all this and the fact that nothing was off (that I could see anyways) until after the UCA was installed. SO either:
1. the solid UCA put the rear end in the REAL correct position since there is no squishy rubber now, or maybe a mount on the rear end isnt quite "in square".
2. the solid UCA isnt made right, and something is slightly off with it.
Say I fix "rear alignment" after installing the adjustable LCA's, and make the gap between the front of each rear tire the same (its a 1-3/4" gap on the passenger side and 2-1/2" gap on the drivers side between the front of the rear tire and the FRONT roll of the quarter panel), will me adjusting the LCA's to this centered position put my solid UCA in some sort of bind, and cause other damage/problems? Should I also look into replacing the UCA with an adjustable one?

Is you axle centered left to right? Do you have an adjustable panhard bar?
Man I really wish we could find the "contributing factor" that causes some people to run in to this issue of the steering wheel going off kilter. Im starting to wonder if this only happens to people that are running lowering springs. Maybe it happens to everyone but some people dont report it or something. Just seems odd that there are very FEW threads discussing this problem.

I think its a combo of the drop springs (throwing the axle to the left or right) then everyone puts LCA reloc brackets on after they lower the car to get ridd of the possible tire hop problem and "correct" the angle of the LCA's after the car is lowerd, BUT the reloc brackets are never perfect because they move the mounting point of the LCA... then you have the rear all out of whack like I do right now.. Did you ever get yours set right?
The adj. PHB did NOT fix my issue. I am sending my brackets back to the manufactor to have them placed in the jig to verify they are not out of specs. If they are out of specs then they will send me a set for free. If they are in specs then they will ship them back and I will order a set of adj. LCA's.
I would have to disagree that the brackets are never perfect. They are made in a single jig that has been pricisevly mesured and if the jig was off then they would alot more than just three or four people reporting our issue. Several manufactors of these brackets sell close to a hundred sets each year.
I also find it hard to believe that not one single manufactor states that their brackets require or may require adj. LCA's after installing them. If the drop springs had any type of influence on what problem we are incountering, the adj. PHB should have fixed it.
