There's a thread over in Expedition Portal where a guy did this swap into a Land Rover. A quick rundown of what he did on his full conversion/restoration:

1967 LR 109"
Mercedes 3.0L 5-cyl turbo diesel
Rebuilt NP435 4-speed with a Pangolin output shaft and adapter plate
Ashcroft high-ratio transfer case
Toyota 4:10 E-locker center differentials in Land Rover housings.

Here's the link: http://www.expeditionportal.com/forum/showthread.php?t=8169

There's way more that hes done to it (400+ posts). I look forward to seeing the progress on your project. <img src="/forums/images/graemlins/kewl.gif" alt="" /> <img src="/forums/images/graemlins/cheers.gif" alt="" />
