Check out the RWD 700/900 FAQ and you might find some excellent tips on getting it done. I have a 92 960 wagon that I had to re-secure the motor after the rivets ripped their way loose. It's not terribly difficult. It is a cramped space and probably the most difficulty will be taking the panels off without ripping the fabric or breaking one of Volvo's ingenious and unique connectors. Like any other job, hopefully done just once, it will take you much longer than the professional so plan accordingly. If you're prone to using golf language you might want to think about keeping small children out of ear shot. You should be able to do it though.
