Outer Limits 4x4 Board

Hi all, just want to pick your brains. I just bought a 1999 FZJ105 Cruiser.
I'm looking to source some rims from the States but I don't know the stud pattern or backspacing. The cruiser doesn't turn up for a while otherwise I could have measure them.
Thanks Regards Mick

See if its in the Toyota Bible (assuming there is one, I dont peruse that section)
