Installed new spicer u-joints on my 67 sb drive shaft and find after installing the lock washers and nuts there are not threads sticking out beyond the nuts after torqing. They are almost flush. Used the old u bolts with new nuts that are the same size as the old.

Re: Drive shaft
Dick,
Assuming that the outer diameter of the old and the new end caps are identical, you may want to ensure that the end caps of the ujoint are fully seated in the housing. A roller may have tipped sideways during installation and is lying crossways in the cap.
Bet you can guess how I know.

Re: Drive shaft
Check for paint or dirt, and compare the sizes of old vs new joint. Any of these can keep the new joint from seating fully. Also, if a bearing roller gets out of place, it can get between the cap and bearing, causing the cap to stick out too far. This will also keep the bearing from seating fully. Extra stiff rubber seals can make it difficult to compress the ends of the bearings fully so they fit down like they should.
There are typically small ramped areas at the outside of the mating surfaces which center the ends of the joint bearings. The bearings must fit between these. If the bearing is too long for any reason, it won't sit flat on the mating surfaces.
Check first that the parts fit and seat fully without bolts, don't use the bolts to pull things into place.
Good luck!
