Oil filter relocation kit?

In the middle of this myself. You’ll want two of these:
JOES Racing Products 42030 JOES Racing Products Oil Inlet Fittings | Summit Racing

As noted above, drill and tap the currently untapped hole to 3/8 NPT, the drill and tap are available as a kit many places. This is the oil supply to the filter.
Then plug the big hole (return from filter) with a 3/4x16 like this one:
Dorman 65226 Oil Drain Plug... Amazon product ASIN B000C11GJ6Then pull the 3/8 plug from the top threaded hole for return back to the engine.
Best picture I got on my phone of it:

I’m not done or I’d show you the finished product. Hope that helps!

Note that the picture is upside down, so the bottom hole on the right is the top hole as the engine sits in the car. So, that’s the one that’s already tapped from the factory with a plug in it, and is the return.
