Right, that's "the downside" of just locking the manual hubs that COTrooper mentioned... Just didn't clarify that this would be the downside of just locking the manual hubs instead of converting to auto hubs.

That being said, there should be many people out there that have the auto hubs just lying around rotting, unless they all threw them out... Someone should be able to send you a set. *If* this is a street-only truck, you'd honestly be better off with the auto hubs anyway, since there's really very little downside to them on the street. On the trail however, they can cause you problems because they unlock briefly when you change directions and can keep you stuck when you need them most. But if the truck never sees any trail time anyway, go with the autos...

HTH,
