diff isnt that hard to do. take the longer axel out, chop it th diff down by 100mm (from memory) with a metal cutting drop saw, send the axel to an engineering mob for bit ova 100 buks they'll chop it by exactly 100mm and respline it for ya.
(i think i may have made that sound rediculously simple, but honestly it aint that hard so long as u get ure measurement correct and cut square you'll b sweet)
