These sound like leftover Bondurant trannys. They used a hardened euro differential & zetec FD. The SVT got the hardened dif in 99..prob the same as the earlier Euro dif but I'm not sure. Doubt if the upgrades include the late MY 2000 syncros. Still, its a great price if you have big power. Stock SVTs will accelerate slower with zetec FD.
