The car 12 is a bit stronger than the truck, the pinion shaft is thicker on the car.

You'd have to get new axles probably, with big ford bearings pressed on though, but if you were going to be buying custom axles anyway it doesn't cost anymore to got this route other than the ends.

I allready have Moser axels, if I understand correctly I can have bearings pressed onto my axles. But that is the route I would take, changing the ends, I heard the eliminator kit leaks, next person says there fine.

While this is true, this is not the weak link on either rear end. The weak point in the design is the contact patch between the ring and pinion gears. You will not see any truck 12 bolt fail by twisting the pinion shaft...
