i just took many pics as i can at each time i remove something.
i start to remove all i can on the playfield and so i need to disconnect some connectors (flasher, contacts, etc) underneath the playfield. you can use some stickers to mark each connector, it will be easier when you will built it again.
Then i go underneath the playfield and unscrew all. Jet bumper are removed at the end, you have to desolder the wires and then you unfasten to remove the socket lamp. there is no other way to do.
TAKE PICS AND PICS.
