BTTF is actually pretty straightforward to remove the ramp from. You should just have to unplug the connectors for the switches and the two banks of lights over the ramp entrances and feed them up through the playfield as you lift up the ramp. Remove all the screws and nuts and it should lift straight up and off. I'm not near my machine right now, but I'm thinking it's 2 screws at each ramp flap, three nuts or screws across the back edge and two or three screws or nuts holding the long part of the ramp.

Can someone please help me out with this?! I have never had so much trouble removing a ramp before. It's still attached somewhere along the back. I see to screws on either side that may be what I need to remove but I can't get a screwdriver to the screw playfield down, playfield up, head down, head up... Any suggestions?
