I enjoyed all the additional photos! Very pristine truck.
Few comments. Interesting it comes with the 15x7" version wheels. I thought that vintage came with 16x6"... Are you going to miss the split rear seats that your Prado had (and third row)? I have to admit, the LJ78 has fancier seats/interior than the HZJ77. I love the dual e-locker setup you have. I have a rear e-locker, but will eventually put in a front. Thanks to your picture now I know how to drill out the front diff in the instrument cluster picture for a second red LED.

Fourth, I recommend 255/85R16 with a mild soft lift.
Have lots of fun with it!
