Have you tried calling a tranny shop for advice? My 124 manual is on my old computer, but I'd swear from what I remember that you shouldn't have to resort to those methods to replace the center bearing. My old tranny guy up in NC did the flex discs and center bearing PLUS all the external seals on the tranny in less than a day.

Don't quote me on this, but I seem to remember that you have to undo the coupling between the two halves of the driveshaft. Then, on the part that has the center bearing, the coupling end screws off and the bearing should slide or screw off the driveshaft then.
