Thanks Rooster for your comments.
I plan on simply removing the 6 flange bolts at the rear of the drive shaft, where it connects to the flange on the differental, then secure the drive shaft from moving out of the transmission by mounting a simple U shaped bracket for it to rest on once it is disconnected. Then further securing it by some means such as bungie cords, wire, duct tape or bailing wire.....
Seriously, I would secure it so that it would not slip out of the transmission.
I have also heard that the bolts are very hard to initially break loose, so I plan on having something to help me break them loose, then keep ample spare nuts/bolts to put back in when I need to reconnect.
Any other ideas, suggestions or comments?
