It's easier to do, if you follow the recommended procedure. I imagine that everything that must be removed seems a bit daunting at first and truthfully, it is. The problem stems from accessing the four bolts that drop from a hole atop the crossmember and bolt into the top of the differential cover. It is possible to remove it this way, but you'll be doing it blindly and relying on "feel." Lining it back up is no picnic either, with everything still in place. If you're planning on using RTV, you'll probably end up smearing it all over the place, also. You could give this a shot, but the frustration I experienced is really not worth it.
Chris had mentioned once, when this topic came up, that you could cut into the fiberglass from the inside and get at the bolts. The problem is repairing the hole, which would probably be best done by fabricating an "acees panel" and using a gasket. There's no simple solutions, I guess.
