I can't remember where I got mine but I did find one somewhere local. A hardware or plumbing supply store I think.
And just a heads up to make sure you get it mounted low enough to clear the #3 rod. I wound up taking my oil pan off close to a dozen times trying to locate the 'knock' I had when I put mine back together. It was barely noticeable when I fired it up but on revving it would raise its ugly voice and scare the bejeezus outa me cause it sounded like a rod or something really wrong. I pulled things apart and checked and rechecked but couldn't find the origin of the knock.
I was so depressed for months trying to figure it out I just about gave up. I finally set up my video camera and recorded the engine turning over with the pan off. Then I checked the sound track in my software editing program and saw where the knock occurred, then I could see it was at the bottom of the #3 (or is that #4?) stroke and the only thing possible was that return line. It was just barely missing the line when I would turn and check by rotating the crack by hand but once the centrifugal forces came into play it no longer missed.
just a heads up for when you do find your fitting and slip things back together... I wouldn't wish that head ache on anyone else cause these engines are really kinda fun to work on.

One more thing I've mentioned in other threads but don't know if it applies to the 235's (mine is a 270) reverse and tap the bottom 2 bolts that go into the bottom of the timing cover from inside. I'm not sure why they engineered it that way but it makes life easier when they are all on the outside in my world.

good luck
