Thanks for the input guys, and i agree with you both. I am actually in the process of parting out my old D30, but will have to make a short trip with it soon, so I will be driving without inner shafts, but need the outers to hold the unit bearing together (I experienced this failure personally when I was younger and dumber). I don't see any problem with running only outers for a while... (?)
Since I plan on selling my shafts as a set, I don't wan't to take off the outers just for this purpose. I figured someone who has blown up a ujoint and taken out an ear, swapped a hub kit, or swapped to 297/760 shafts has a set lying around taking up space...
