I did the same swap last year. Seems to be a trend of just measure it when you get it in. Many told me to shorten it by as little as 1" some were clear up to 1 1/2". Well my car is a back half car w/ladder bar rear. I had to make no changes. I wished I hadn't made so many changes when I added the Dana years ago to my other Duster. Started from scratch there. Just measure & make sure it's right. Sorry thats the best info I can give you. Thanks, Ken
