They are labeled RH and LH. The RH spring was 30mm taller. There was a sticker on the springs that said "Instructions are for Australian models. For US models, install the taller spring on the driver's side!" When I removed the old springs (which had 65k on them), the taller Toyota spring was on the RH side. But when I specifically emailed Tough Dog they said:
"In RHD vehicles, the Driver sits there so a slightly higher coil is fitted to cope with the slightly higher weight. Usually the higher coil goes with the Driver side, so in the US the LHD side would take the higher coil. Coil rates as the same for both sides".
So when I did the install I put the taller spring on the LH (drivers) side. Tony, if you didn't put the RH spring on the LH side like me, that explains why you are level and I am not.
I need to crawl under the truck and measure the installed spring height on each side. Assuming a ~20mm difference in compressed height swapping the springs should get me perfectly level (i.e. reduce the LH side by 20mm and increase the RH side by 20mm is ~1.5"). Most likely will be labor day weekend before I can actually swap them though.
(I'm assuming btw that most of my front difference is due to the rear spring height being incorrect and that it will level out when I swap the rears... if not then that will be my next issue).
30mm difference! Over an inch, wow. Umm, I'm sorry, I didn't know they were that much different. The stock and OME springs are within 10mm, which is all you need to compensate for the weight of the fuel tank. The front of our trucks is incredibly well distributed so no difference of coil height is needed in the front. No wonder you have lean, good god, this is why I keep going back to OME, never been a tough dog fan. So yea, I would still put higher spring on passenger side, the steering column, master cylinder, and battery don't weight as much as the fuel tank/pump and 155 pounds of fuel, and the spare sitting on the passenger side.
The alignment shop I went to is awesome. They do nothing but suspensions and alignments and specialize in track cars and lifted trucks. It's two guys (one who is probably 60 and owns the place, and a second ASE-certified suspension guy who has been doing this for 10 years). IIRC he said he set the front right caster as far positive as it would go, then set the camber as far negative as he could (which was still almost 1 degree positive). Left camber was set 0.5 degree lower to compensate for the road crown, and left caster was set as far positive as he could reasonably set it while keeping camber within spec. He said he also set the toe closer to 0 as he could since the A/T tires are heavier and stickier. He definitely had to pop the cam bolts loose to adjust them. Here's the printout:

If you have alignment specs you'd recommend for my truck let me know and I'll get him to readjust. I'm going to put a set of SPC UCAs on since I want more caster and a bit less camber, particularly for towing (which is probably half my driving every year), since my steering feels a bit loose when I'm loaded way down, so I'm going to need him to realign anyway.
Since you talk about different length driveshafts causing torque steer, that makes me think the issue is related to my lean. The left side is higher, so the CV angle on the left side is steeper. Not sure if this is right but I'm envisioning walking around with my left shoe on but not the right one - leaning to my right because my left leg is longer, and consequently my left leg is pushing me to the right. Tony, I assume you don't have any issues with your truck pulling under acceleration? My pull is definitely stronger the harder I step on the pedal.
I didn't mean to question the shop you choose or the people behind it, not my intent, but as most know on this forum, it's hard to impress me, but I'm not a hater, I just question a lot in an attempt to find the "best" I can of something. But so you know, I've had A1-8 ASE certifications for over 10 years also, never took a class, grew up in a shop and learned from custom car builders. And one of those guys, Frank Linney, would always tell me to "be careful of the guy who says he's been doing it 50 years, he doesn't want to learn and get better, so he will never be a good builder." I took that stuff to heart, which is I am who I am.
You are cross cambers to the RIGHT! so whoever did the alignment has never heard of road crown or didn't care about it, the side with more camber is the direction the vehicle will pull to. So that alignment shop that specializes in suspension set you up to pull right on top of a road that drifts you right.
Caster, you are about 1.5˚ from factory spec, that would explain wander, not the shops fault, but an aftermarket upper control arm would be of benefit. I personally prefer Total Chaos, but SPC is fine as the strength is only slightly, and I mean slightly weaker than stock.
Toe: they toed in your left side (a bit more for my taste, but no harm done), but they didn't toe in your right, so your left wheel is pushing right, but your right wheel isn't countering back, so with every bump, you continue to get pushed right, adding to your constant rightward drift and pull. The term "toed in" is to set both wheel in about 1/16" to 1/32" (I shoot for 1/32" per side, not 3/32" like your left) that makes the two tire high against each other to cause the truck to push strait down the road, instead of fighting to get away from each other cause more driver input.
I would give my specs, but you need to at least start from a good base instead of the bad alignment they gave you.
Front Caster 2.9±0.75
Front Camber 0.13±0.75
set your left camber to +.6-.8 and go UP from there. You can go as high as +1.5 before any additional wear happens
Front Toe (degrees) 0.24°±0.16°
Front Toe (inches) 0.12±0.08"

@linuxgod, I absolutely do not mean to come off like "look, I know more," I'm truly genuine and just want you to have the best you can have because you've worked hard for it. But this was just another case of, "these guys are great." No... they are not, in fact in my small opinion they are very thick headed if they think that was a good alignment, they are what Frank warned me about early in my life, someone been doing it the wrong way their whole life, and making you have to deal with their limitations. Because obviously, almost every part of your alignment is going to pull you right.
