Trying to Cram In An Oil Cooler

Winter is over, the crocuses are blooming, and it's time for me to get my oil temperature under control. In the past race it was somewhat north of 245 deg, which is way too hot.

I found a nifty auto performance part called an "oil cooler sandwich adapter". This is pretty nifty because it includes the 180 degree bypass valve. Here are a couple of photos.

It mounts right on the El Reno style spin-on filter adapter, easy as pie.

That was the easy part, now I have to find a spot for the cooler itself. I got a cooler which is sized for the O-300D engine, which may be overkill, but since it was only 1/2" taller than the O-200 version I figured I may as well go for the extra cooling.
I guess I'll just order some hoses and fittings and plumb it in. The next hard part will be making some kind of ducting to feed it.
