    I'll second that. I ordered one recently from Rabidchimp and their service was excellent. The guy's name i dealt with was Aaron. Total was $758 AU including full insurance and snail mail shipping (4-6 weeks).

    I've got two F LSDs kicking around (not counting busted ones!), but I suspect they're both pretty tired. For that matter, I expect that any you find are probably fairly tired by now.

    Its a bit noisey at first but its gettin quiter as it wears in.
    It cost us $600 walk in with the diff then pick up the next day, no more to pay bar for the oil.

    I havent driven on mine yet but my mate said its a lot better then the one in his ma70 which is a torsen lsd.

    Cheers

    the truetrac is a torsen. Although probably better design then the toyota factory units.

    I believe Truetrac and Detroit Locker are the same company, so I think you'll find you can either get a torsen LSD or a locker to suit most cars from Truetrac.

    But the ones most people are getting from these forums seem to be the torsen variety. I know mine is.

    The Truetrac is their Torsen diff. They also make a locker. The company that makes them is called Tractech (?).

    OK, I'm looking into where to buy a TrueTrac.

    Anyone found a place in AUS that stocks them?

    Im looking at getting one aswell for an MX73, I was thinking of Rabidchimp aswell because you get the carrier bearings aswell yeh? I would do a group buy with ya but we would probably lose out on the customs fees
