Preparing the car to cut out the floor, the driveshaft should be removed as well. It's also a key moment because the front and rear of the drive train get officially separated... It's not a hard job, at least it wasn't in my case.
I had the rear lifted a bit because the rear wheels are on dollies now. I could slide underneath the rear axle easy and get to the U-joint. To get the driveshaft out you only need to undo the nuts on the U-joint next to the differential, push the shaft forward a bit into the tranny so you can lower the rear and then pull it out of the tranny.
So starting this procedure with getting the nuts off of the U-joint:
And if they are not rusted and stuck, you have the shaft out within minutes:
Done!
