Remote Oil Filter/Cooler

I am trying to source an engine block off plate to use with a remote Oil filter. I plan on using AN-12 fittings & hose and would like to route lines direct to block ('72 350R) & not use a "Spin-on type" Adapter.
I know Nunzi makes these for Pontiac but can't find any for an OLDs V8

TIA
