Is there an aluminum case posi unit made for the 742?

Is there no problem with gear oil migrating through the bolt tubes and leaking out of the front side? It's a fine looking piece for sure. Since it's aluminum, I wasn't thinking about the strength factor, but from all of the ribs and the huge bearing caps, no doubt it is stronger than a stock piece.

Let's hope not, that would be a big problem. Those are through bolts for the caps.
