My mistake, I bought it with a SBC oil cooler that necks down to this remote adapter, and the adapter was the thing that mated with the SBM oil plate. The SBC adapter says "do not use SBC oil filter, use FRAM PH-25". Confused myself as I had to look back a the Ebay link for a pic. Its the somewhat generic spin on 2 port fitting that threads onto a stock MP nipple and has an O-ring.
