Hey Dave,
the one we've got came from JCWhitney. I think the 240 uses the same pattern as Fords.
Plus, I think there's a couple different types of "sandwich adapters" out there. There's the "remote filter" type of adapter which is strictly for creating "IN-OUT" at the oil filter mounting point. And then there's the one which is truly a "sandwich" in that you bolt the adapter to the mounting point, and then screw the filter to the adapter. The adapter has the "IN-OUT" ports.
Some people don't like the true-sandwich because at high psi it has a tendency to blow filters off. Others prefer the "remote-filter" type, because well it allows/requires the relocation of the oil filter.
FWIW, we're using the true-wich, haven't had problems running up to 60psi. I've seen others with the remote-filter.
