tranny and rearend swap

Hello all, I'm in the process of swapping out my 904 tranny and 7 1/4 rearend for a 4 speed and 8 3/4 in my 69,Dart. Will my driveshaft work or will I need a different one. Will a driveshaft from a dart that had a four speed and 8 3/4 rearend stock work or will I have to have one made? Anyone out there already done this and how difficult is this? If so, how long of a driveshaft is it?
