Outer Limits 4x4 Board

Hey guys, has anyone done this or seen it done? I know they do it with the 80 series but can it be done with a 105?

Been done in Melbourne, by a guy on www.lcool.org
Apparently quite easy but u need to consider putting in an 80 series h151 gearbox with it or u will suffer gearbox reliability issues (hz105's use prado r150 gearbox and transfer is different too)

Thanks Andrew, I've posted my Q? there as well, have had some feed back from Greg on other bits and pieces.
