Saw this on Marlins BB yesterday and it got me thinking...
I started thinking of how to build my own out of parts I had. After drawing up what I had in mind and staring at the top of a stray t-case, another idea hit me.
What if you ground down the tip of the shift lever, and ground a little off the chunks that the shifter engages. That way if you're in 4lo and want 2lo, you can move the shifter to the middle and swing it between the 2 chunks, then move down and it all the way over to engage the 4wd/2wd selector. Then you can shift up into 2wd leaving the other side in low range.
Maybe this pic (below) will help explain. On the left would be your shift pattern. Still use the standard J pattern til you want 2lo, then follow the red line, and reverse it to go back to 4lo. On the right is what's under the shifter. The blue square is the tip of the shifter and the red is material to be removed.
I tried to measure with a tape, but might be off a little. Looks like the tip of the shifter is 6mm, and the notches that it engages are also 6mm deep. There is about 1mm between the 2 chunks. So that's 13mm total sideways movement of the shifter. If you grind down 2mm of the chunks in the red spots, and 1mm off each side of the shifter, it should clear and leave enough to shift easily.
That would make it 4mm deep at the notches, and the shifter would take another 4mm. Then there's still 1mm of clearance.
