I got the oil filter socket, oil filter, oil filter housing o-ring, and oil filter housing from Pelican Parts.
I never did get the oil filter housing away from the car to put the new in it's place (not sure if that is necessary, but I bought one anyway), but using the new rubber o-ring left me feeling pretty comfortable.
The above pictures should show the hose ID and the length that I cut that worked just fine.
I let everything drain for a couple of hours with the drain fill cap removed and covered with a rag.
Here are some somewhat hard to describe and understand pictures until you get under there and struggle for yourself. The drain hose is shown where it attaches to the oil filter drain and also the green plastic is part of the headlight aiming apparatus (?) that I did not try to remove - which should have given enough room to replace the filter housing instead of just the oil filter.
