Hey guys, may be a silly question, but is it possible to lock the 4wd mechanism on the brumby and take out the CV joints to make it RWD??

If so, what are the pros and cons. I'll be honest here, all i basically want is oversteer :Dwith minimal/reversible mods. Can't give it the old scandinavian flick because all i get is understeer and in 4wd its next to impossible to get the thing to let go.
Cheers, Pete
