Removal isn't that tough but I wouldn't do it just to install the drain, not that hard to do it in the car and steel_blue_91 had a great suggestion to use the fuel line as a drill stop. You need to remove the exhaust, rear spring, rear toe link assembly, unbolt the camber bars at the differential and swing them down, unbolt the driveshaft and both half shafts and remove the rear bolts from the support beam, finally the two bolts attaching the batwing to the frame. The assembly then drops out, but you will need to remove the cover bolts to separate the batwing from the pumpkin. I'm sure someone will remind me if I missed anything.
Your definition of easy is a little more liberal than mine. I just got done replacing the rear hub/bearing units, so I know what a PIA some of that stuff was to get off, and I don't even want to think about how rusted the bolts on my exhaust must be. I am dealing with a 1984 Corvette with 180,000+ miles, and as near as I can figure, a sketchy history. I also only have jack stands to work with. It may be heresy, but I think I will take my chances with sucking out what I can after running the car for a little while. It may not be optimal, but it will sure beat doing nothing. Thanks all for the input.
