auto to 4 speed, what do I need

hey guys I have a 68 dart 440 727 auto. I want to swap to a 4 speed, the car will be street driven, the 440 is semi mild. I need a complete list of parts I will need. and what spine box is needed. Also things to look out for like drive shaft length ( will my current drive shaft work) I want to start lining parts up now and do the swap next summer. thanks guys.
