I really need to pay attention! (Z-bed hinges)

[NWbuspilot]

I guess I need to spend more time in the back of my bus. I was so used to having the z-bed in the back of my old 66 that I didn't even realize that I had Z-Bed hinges on my rear seat! Now I'm just going through the impossible task of drilling out the permanently rusted-in-place screws holding the plate down so I can clean up the hinges and the floor under the seat. 3 drill bits down and 2 screws out!
