Lookin at the Lee's pictures, it seems the building instructions are the same for atleast the shock tower/arm positions and the rear sway bar... I just used the included oil for rear diff, and 10000 for front diff.. Going to test it out next saturday..
Building it from the manual.. there's certainly some thought in the setup there, its not just "put everything in the middle position". Only thing i'm bit concerned about, is the amount of limiters in the rear for bumpy or big jump track.. 501 had a tendency for grip rolling also. Considering that, maybe 4wd doesn't need that much of travel in the back.
Need to drive it first
