dart vs. duster driveshaft

Hey all,
i just want to make sure... a 73 2 door dart will have a longer driveshaft than a 73 duster, correct? I believe that the dart had a 111 inch wheelbase while the duster only has 108. I'm looking at an 8.25 to swap in and it would be a lot easier to buy the accompanying driveshaft than get mine shortened. Thanks.
