For the oil feed, most people seem to use an oil filter sandwich plate. Like this:

There are plenty of companies that make them, I jsut posted that particular link because it was the first one I found with a quick google search.
For the oil return, you need to tap the oil pan. You'd use something like this:

Again, this is just an example. Specifically look at the 2nd pic on that page. The part with the 2 bolts going through it attaches to the oil pan, after you drill the holes for it. That thin metal line in the pic is actually an oil feed line, that happens to come with that kit.
