Do you know how to get the replacement nut/bolt for the door? My spring is ok but the nut/bolt is wearing out, when I took a picture of it Google seems to think it the guide for rolling down a Chevelle rear quarter window?? Weird, does look similar, no idea the size, I have tried to look at many schematics and I never see this part listed. It is the part that the lever that the door slides up and down on that is connected to the side of the toaster oven. Thank you.
