The longevity of the rear end will depend on how you plan to drive the car... What trans are you using? The rear will probably live for a long time if you are running an auto with skinny tires. A 4 spd can shorten it's life "IF" you can get it to hook up. If this is an open (non-posi) differential and you aren't planning to run super sticky tires I doubt you will have a problem. Your biggest hurdle is going to be to get the car to hook up with the stock leaf spring suspension and stock open rear. The deuces little wheel wells will limit the size tire you can use anyway so, unless you are planning a major tearup to fit bigger tires, I can't see to much traction being a problem. This, in itself, will limit the amount of "shock" the rear end will see because all you will do is smoke up the small tires with your 450 horses...
