Thanks for the link. I figured siphoning it was the obvious way (I'm a bit of a gear head and have had to siphon more then one differential). Did some digging and found this

so I am guessing I just need to get a "T", a plug and a fitting to hook the "T" to the pump. I really would have liked to go with the hard tube one, I like the way the rigid lines look....which is one of the reasons I am asking about a drain. I have a friend who is REALLY good at bending brake/fuel lines who has volunteered to bend the lines up for me...he just is out of town until mid February on a snow mobile trip and I don't want to wait that long. Thanks again for your help.
