Lets begin. Ive done this exact thing on another truck forum I belong too and it turned out wonderful. The name of the game: I make a list of all the tools, parts, steps, modifications, problems, custom parts etc. needed to do this swap. Orginize them, have people fill in the banks who have also done this swap before, I make an organized list, update it as we go until enough info is needed to do the swap, and boom. I do a full write up and add pictures. Ive been reading multiple forums, questions, threads, write-ups, and cant find one from start to finish with pictures, and important 1st hand tips and tricks (though I did find tons of info). This should sum everything up...hopefully.
My rig in question is a 1986 m1008. but this should apply to all cucv's. Im not a fan of auto's to begin with, and with these gears its killer (I do plan on upping the tire size). My th400 is beginning to slip and decided I might as well satisfy myself and go the extra mile and do the swap. Here it goes.
parts needed (used)
parts: (new)
Mods:
I can get into detail about removing the auto to make way for the new, but that can be covered later. For now I just want to get the lists worked out before we start talking about wrenching. Like I said, you guys can add stuff, drop some hints or tips in, correct a few things, and as I learn I will update the list by adding or removing things until we can eventually make this a full write up from start to finish.

parts needed (used)
- nv4500 (np205 or 208? could the stock 205 be used? What year 4500 is most desirable and does gas or diesel matter?)
- all appropriate gear selection sticks and 4x4 stick...if its not included with trans...
- clutch pedal and bracket
- slave cylinder and hydraulic lines
- speedometer cable?
- flywheel (I know its been mentioned, but which flywheel would be used?)
parts: (new)
- Clutch kit (should come with Throwout bearing ad pilot bearing)
- (might as well put slave cylinder down here as cheap insurance)
- shortened front driveshaft and lengthened rear (this is where the tips and tricks come in...have you guys found anything that fits stock?)
Mods:
- instead of locating a new bellhosing, I head its possible to grind and modify the existing for clearance issues.
- drill hole in the floor (should be stamped in the right spot already) to plumb the clutch line
- hole in the trans tunnel for new shifters
- does the crossmember have to be moved forward or backwards on the frame? Or will it bolt in the existing spot?
- custom driveshafts
- jump the plug to trick the truck into thinking the "no longer auto" transmission is in park or neutral...so that way it will start lol
- remove auto shift linkage (I believe you can leave the column shifter in place)
