Outer Limits 4x4 Board

Can some one shoot me a link for some where (inAaus?) to get 5th gear parts / kit for the series 1 Rav4 as it jumps out (common problem apparently) have trolled the net and have only found one place in the US that wont ship to Aus, has toyota got the market cornered with its own genuine parts or is there an OME site around?
Thanx Dan
