Jim, The part number you need is a plug with a nipple attached. It is called an oil cooler
joint and is made by Honda.
Part number is
11107-pk2-003 for the plug
12207-634-300 for the crush washer

if u look at the back of the b20 block, there will be 2 hex nuts on each side of the oil filter receptacle. all u need to do is unscrew one (the one closest to the battery is usually preferred) and screw in the new hex nut with the nipple and that's it. all u need to do now is get some hoses and attach it to ur Catch Can setup from this nipple and then from the PCV valve, on top of the catch can, to the intake manifold. Here is a picture of what the catch can set up should look like.
