904 giving up the ghost?

Alright here are some pics of the "old" broken valve body... i'm thinking I should get a tray to separate all the springs and pistons to keep it all organized, will I be swapping over anything from the valve body itself to the "new" one (springs)? And what about the separator plate and transfer plate? I'll get the new VB apart and post pics soon.

EDIT: That tray looks dirtier than it is it's an old (but CLEAN) cookie sheet with probably 30 years' worth of baked-on residue, that stuff is not coming off lol.
