I went ahead and removed .5mm worth of shim from the top, torqued it down and...
~8lbs of pre-load. Perfect!
I am just going to assume that the bottom shims created the correct placement relative to the axle centerline and at worst my removing .5mm from the top at worst moved the centerline up .25mm. If CCOT fucked up and the alignment was off before I took it apart it's not going to be any worse now (and I have no reason to believe it they did it incorrectly). Without a SST there's nothing more I could do and I can't wait to find someone local who has one I can borrow.
I also went and bought some moly fortified grease and cleaned the little bit of high-temp grease I had put on the bearings off (very carefully to get it all because i know mixing grease is a bad idea).
The left side, with the same set of shims that were on it originally, came out with a pre-load of just above 4lbs. I'm going to call it good too....
While torquing the left side one of the (new!) studs on the bottom stripped. Son of a bitch!

Thankfully I was able to back it out while in place and had another spare... I backed off my torque a bit (I was doing 74lb/ft) when I put it back on. The FSM says 62-79 lb/ft. I guess in the future I'll go for the lower end of what Toyota recommends vs. the higher end...
On to the hubs...
