SM465 to TH350 Swap...Help!!!

[rub1401]

Hey guys I'm am kind of new to this site and kind of not as I have read many of your posts but have never posted. Anyway I tried to find tech articles on this but haven't found exatly what I'm looking for. I have a 69 2wd 1/2 ton with a SM465 and an I6 292. I have a friend who has a 70 4wd with a
TH350/350. He wants my manual and I want his automatic. What is the process of swapping my 465 for his 350 and what parts do I need to buy to make this happen? Eventually I will swap my 292 for a 350 also but for now I would like to run the 292/TH350. Thanks in advance cause I know you guys have the answers.
