So the front and rear flanges are the same then?  I know I had read that article on clearancing yesterday but I already have an '84 front shaft, so that should be good for 35 degrees in stock form, right?  Or can I clearance that one to get even more travel out of it?  So if I am understanding all of this correctly I should be able to pull the front driveshaft off of my 1990 parts truck and join the CV section with the back half of the '84 rear shaft.  Are the tubes the same size where I can just cut them to length and rig up a jig to weld the tubes together?  Also do you think I should rotate the front pinion up by the use of axle shims, or should the U-joint be fine?  I really appreciate the help so far, so keep it up!
