I don't know about adapting American stuff. Seems like out ctransfer cases are pretty dang tought, only wear out on therear output tailpiece bushing.

There was a guy in OK City with a place called Aierial Performance. Dead or out of bisiness, He had a couple palletes of New V5MT1 or 1-2s. Sold on Ebay. Sure would be good to have a detective in those parts to track down who he sold the business to. Dang it I missed on that one. One of the folks on here got one from him. They're dang though transmission , I preferr to stay with mine.
Good Luck.
