Good to see you get your hands dirty, Rob.
Flipper Bats -This is for the GTB Baseball ? Remove the two screws from the top of the bats and they should pop out. Then you need to go under the playfield and remove the grub screws from each pawl. Once removed, the flipper shaft can be lifted from the playfield.
Pop Bumpers - Under the playfield - Desolder the lamp socket. Remove the two nuts on the pop bumper ring. Top of the playfield - remove the pop bumper cap and remove the two screws holding the pop bumper body to the playfield. They should come out easy.
