Last I spoke to Duffy, he was still doing the kits. That was three months ago. He was planning on dropping the 'kits' eventually and switching to an entire reduction box. The first off was to be the D300 since that appeared to be more in demand. Next would be the NP231/241 sometime this spring.

I think there's some confusion. None of the kits or boxes on the market come with adapters specifically for Mitsu anythings. As Toasty pointed out, you can mount the NP231/241 to a Mitsu automatic transmission with the proper tailshaft, output shaft, etc., as Nathan did, but you're on your own otherwise.

This is my Sport conversion but there's tons of pictures which may be helpfull.
