Driveshaft length

The difference of the two rear ends is .66 and the difference of the two trannys is 4.01" so if you add the two your driveline from center to center of u-joint should be 4.67" shorter than what you have now. But like the other guys I would be very leary of shortening it before the swap.

These measurements I quoted are right from the Mopar Chassis manual so if it is not right don't shoot the messenger.

One other thing to consider your Duster has a 108" wheel base while Darts (except Dart Sports) have 111" so if someone quotes you a length make sure it is a Duster type 108" wheel base car.
