I would recommend giving Lloyd over at RBT transmissions (CA) a holler The freight to get it over via a carrier is min. in comparision to the workmanship (guess maybe $100.00 but Lloyd can help you know for sure)
They bought the rights to the ZF and have developed it further to include the 6th speed unit used in the supercar Saleen put together. Their info is contained on http://www.rbttrans.com/
A couple of the Pantera Vendors like Dennis at Pantera Performance in CO and others also do great work and you might consider them as well.
Good luck..
