Hi Chris, Welcome and many happy returns.

I would steer you away from the lock right in front. I don't know what if any experience you have with those, but they can make it tougher than nuts to steer - even with a saginaw PS. And turning on top of Sand Mountain will be a concern. Even the No-Slip locker is better, but if you can't go with a selectable, maybe think about something like an Auburn LSD.

The Aussie in the rear is good, but you could put that up front and live with a lock right in the rear until you can afford to upgrade. It's much easier to deal with the rear pumpkin since you don't have to mess with the front drive shaft and worm gear.
