Dusty,
You can use one in stock and MOPAR (if they are still in business) pays contingency. The problem is when you break a rear end it will usually break the aluminum housing. Been there done that. I asked several manufacturers if they can fix it and they said no ... they are about 11 lbs. lighter than the cast one and are not suppose to flex as much, but they are expensive and won't take the impact of a rear end breakage ...
