I did this job on my old '71 250. I didn't have to remove the whole drive shaft. I simply disconnected it at the tranny end, undid the bearing carrier from the chassis - and here's the iffy part - I used a Dremel to cut through the old bearing carrier and bearing. Since I was going to replace these anyway, I saw no reason to keep them. I actually stopped a few mm short of the actual shaft and used a hammer to snap the bearing off so I wouldn't damage the driveshaft. Once these had been cut through, it was easy to slip on the new carrier and bearing. I'm not sure how different your driveshaft and components are but they should be similar. It might be worth looking into - much easier than dropping the whole driveshaft.
