I'm trying to remove the original oil filter plate, but the big 1 1/4" nut has such a low profile, even when i can get a purchase on the nut, any pressure on my wrench bar just tips the socket off the nut!! And the position is too akward for me to get a hand up in there to hold the socket on.

Is there a trick?  Turn the wheels one way or another to get the steering linkages out of the way?  Or use a open-ended wrench? How have people gotten in there with enough leverage to get an old nut like this out?

Thanks, Nate
