This build started as a BW1350 twin stick & it can be done the doubler case goes behind the t-case but i'd have to build bearing blocks, shafts, move rear axle back and more modifying than I wanted to do so i opted for what all RBV wheelers do, a doubler. A lot more to it than posted here. But here's the skinny of it.

Shifter linkage. This was the hardest part I opted to use manual shift cases cause I don't like electric shift. I had about 2 days of design in it trying to clear everything & make the shifter & arm on the t-case travel the same distance on a different radius

Everything installed (I hope again)
