8 or 10, don't remember exactly. Remove them with a socket and extension. There is also one in the center of the pad on the small section that drops down on the dash pad just to the right of the heater control. Floorboard up is correct.
yep there are about that many lining the lip of the verticle dash face. I think there are some also near the heater outlets but cant remember exactly. Removing the instrument cluster and glove box like said you can see them easier. I laid kinda upside down, head n shoulders on the floor boards and my ass on the seat looking up with a big light to find them all. Not fun but doable and a deep well socket helps also cause the studs are a little long.
