Factory Oil Cooler Removal? help please

[sled_dog]

Trying to get to the junkyard but want to save the factory oil cooler setup off my 85 K5. I got the lines and all removed but how do I remove the part that the oil filter screws onto? Does it just twist off like the oil filter?

There are two allen head bolts that hold it to the block.
