Steppenwood,
Here are some NAPA numbers that have been posted in the past.
1006 for a Fram canister.
1100 for one of the AC canisters.
Not sure what Curmudgeon is suggesting about the Fram canisters. The Frams I have seen do not drain out the bottom in terms of draining all the way to the bottom. Do they have a tube in the middle that keeps all of the oil from draining out or do they have the outlet on the side (and thus all the oil does not drain out - you need a siphon to empty the Fram canister)? The AC canister that I have on my truck drains all the way to the bottom.
