What's an 833 o/d from a truck worth?

You can still use steel bushings in the aluminum cases to reinforce the countershaft. Or switch the entire thing into a cast iron case. Do either one of those things, and the 833 OD will last just fine.

No, its not as good as some of the alternatives, but for $200 and maybe an extra $100 to bush an aluminum case or buy a cast iron case you're at a fraction of the cost of any OD alternative. And, unlike any of the 5 or 6 speed options currently available, they bolt right it. No, the gear ratio's aren't perfect, but its not a "race" transmission. That Passon 5 speed would sure be nice.
