Anyone dismantled these driveshafts?

[30psi]

I wanted to inspect the shaft inside. The design of the early shafts is actually carried on from the 280zx and 910 series. They were running UJ's before that and obviously didnt think people would ever want to take them apart until in about 1986 someone used their brain and decided on the later version.

I saw a fekked early driveshaft and the spider assembly wasn't held in with circlips, the end of the driveshaft in 3 places was curled in to keep it secure. That was the hub end of the shaft, but I wonder if its the same on the diff end.
