6 speed conversion

I have an NV5600 6 speed in my 94. It was a pretty simple conversion, as long as you have access to someone to do your drive lines. The 6 speed is like 9 or 6 inches longer. Transfer case will bolt right up if you have a 4wd, but you will have to either modify the shifter or install a 24V 4wd shifter, as the NV5600 doesn't have provisions to mount a 4wd shifter on it. Also, you will need to extend the Reverse switch wiring to reach the location on the 6 speed. You need to go to a junk yard and get a crossmember from a 24V truck with a 6 speed.
I like it alot. The NV4500 did shift faster than the 6 speed, but it was also just rebuilt and I do have a dual disc clutch compared to the single disc in the 4500. I do like the gear spread alot better and we'll see how it tows, but having had 2 other 5600's, one in a 24v and 1 in a CR, I think the 12V/ 6 speed combo is going to be great for pulling.

the ford 6spd is the baddest combo you can put on a 12v for 6sp wise, the g56 IS the lightest duty out ther, the strongest would hve to b the zf 6 in a ford and it will withstand a lot of torque and gear jamming, i plan on putting one in mine instead of the lightweight 5600, just hve to get the time
