I've got a Dana 44 TwinTrac to go into my truck, it come out of a V8, mine is a six, so I need to swap the yokes. Can I just swap them or will it impact the pinion depth or something?

I did a gear swap in my Sunbeam Tiger (also a Dana 44) years ago. My recollection was that the pinion depth shims were on back side of the internal bearing. So, I don't think that pinion depth will be affected. However, there might be a bearing pre-load issue. So, I would wait until you get a definitive answer.

Follow the shop manual and torque the pinion nut to the required torque. The bearing preload is set by the pinion nut torque, the pinion depth is adjusted with shims under the pinion bearing. Some later Dana 44 use a crush sleeve to set the preload but not on our studies.
I'd replace the pinion seal also.

Can someone explain the parts in the chassis parts book on the diagram of the differential numbered 1005-36 and 1005-71? According to their description there must be two adjustments made with shims for the pinion. One for the locations of the pinion in relationship to the ring and one for a bearing preload. Am I interpreting this diagram right? Len.

Correct.
The shims in between the pinion gear and the rear pinion bearing are to set the tooth properly (fore/aft) into the ring gear.
The shims in between the two bearings are to set the tapered bearing roller adjustment.
Some diff's use a crush sleeve. Depends on the MFR and their procedure.
Since you are not changing the relationship between the gears, or changing the relationship between the bearings, you should be all right as long as you torque it properly and to the correct torque spec.

No crush sleeve is there, and I guess that is where I started loosing confidence I'd have a problem.

So in synopsis, a few thousandths difference in the relationship of the back of the yoke and where the nut torques on won't have any effect as long as it is torques correctly. Right?
