SL600 PS Fluid Change

[MB-Dude]

Any recommendations on specifically how to change the power steering fluid in a '96 SL600? For virtually any other car, I remove the power steering return line from the pump reservoir and dump it in a bucket, allow the engine to idle while pouring fresh fluid in the reservoir. An assistant gently turns the wheel stop-to-stop to make sure all passages are flushed. But on the SL600... well, there's no bloody room to get to the return line without major surgery! Anyone ever changed the PS Fluid on a V12?
Cheers,
