hey there guys, i have a 89 ea fairmont ghia and a 90 na series 2 fairlane. the fairlane got ridden off and i would like to know if i can put the diff and drive shaft in to the ea ghia or do i have to get the shaft cut down to suit. the ea is a 3 speed and i want to transform it to a 4 speed useing the box diff and shaft from the fairlane. the lenght of the shaft is my only problem. all help to this matter would be grateful. thanks guys.

yeah diff should fit straight in, not sure about the tailshaft though.
