Land Cruiser Advanced Handling has a kit, 4 brackets and hardware and instructions, maybe $150-200 can't remember. Also need 1 1/2" shackles for the rear to level things out. 4-5 hour install, depending how you spring pins come out. or look in the tech links for ideas.
A little more time intensive than a purchased kit... but grind off some of your old parts and recycle them for something like this. I had to crop these out of some other pics, so not the best images... I'll snap some digitals this w/e should you want a better look.
I used the rear of front spring hangers on the front straight on the chassis, the lift was from using 60 springs with 81 on spring mounts for bush size, and I moved the front diff forward 2" as well, by re drilling spring perch, and centrebolt on 60 spring was about 1" forward already.
I turned the rear spring hanger around too, and used 60 rear springs, redrilled the spring perch, and that moved the rear axle back 4", and I swapped the shock mounts to the rear of the x member on the rear.
