Could you guys help me make a checklist of parts/procedures before I start in on my swap? In the process of picking up a early/mid '70's 455 and TH-400 tranny.

For the this swap I currently have the 307/TH200 3spd auto slow combo. Pretty sure the TH400 is longtailed so I will need a new driveshaft and the TH400 yoke correct? What else am I forgetting? Crossmember and linkage needs to be changed also, right?

Mission of this rebuild/swap is to have a fun daily driver that can lay down some smack every now and then.
