filter less oil pump?
I looked into this as well. Sadly what those down-under are buying is a US spec pump that someone then modifies to remove the filter pad and install the fittings to remote mount the filter on the LF corner of the block out of the way of their steering box.
Most of those that I could find pictures of had the fittings brazed in place. They used what I think are Inverted Flare to NPT fittings, but I's advise using -10 AN/JIC
