Is there anywhere to see full details of the script before PW died.
Not really. This is all we have to go on at the moment:

The original script is mostly the same but for with a few differences
Sean was going to have a big part, he was going to join the team in rescuing Ramsey, heading the Abu Dhabi and the final sequrnce in LA.
-Hector was going to have more than a cameo, he was going to help the team in their fight with Shaw and Jakande at the end.
-For the ending, the crew celebrate in a diner and Hobbs shows up with the secretary of defense who gives Dom a clean record, but Dom decides that he and the crew are going to be outlaws much to Hobbs' dismay throwing the clean record out of the window. Dom gives the secretary the God Eye, which turns out to be a fake and instead it's a video of Roman dancing.
-Dom and the team then use the map of the God's Eye to know where they want to go to next, Brian asks this to Dom, but Letty repsonds by saying "Let fate decide".
-In the post credits scene, Deckard is revealed to have survived the rubble and instead disappeared and sitting in a room with past villains from previous movies, Johnny Tran from TFATF, Carter Verone from 2F2F, Braga from F&F4 and surprisingly Zizi from FF5. A mysterious woman (possibly Charlize Theron) enters the room and tells them that they have work to do.
I'd say the initial final draft (before PW died) they took Sean out and reduced him to a cameo, same with Hector.
