Peter, a 5DS-25/2 ZF weighs 155 lbs without a bellhousing so needs a substantial wooden crate for safe overseas shipment. They are not cheap these days and shipping is high cost due to the weight. There are also quite a few options available in gearing, LSD etc; contact Lloyd Butfoy at <RBTTrans.com> in California (mornings- he's a busy boy!) for a certified rebuilt assembly with all-ZF parts. His company bought all the rights, tooling and spares from ZF in Germany, back in the '70s. He also offers a 6-speed version.
