Putting it back in. Took decent pictures of wiring and connectors and am finding most of what I need.

can someone tell me what the top screw is supposed to screw into? I was expecting some threads. See picture.

Thank you!

 

the screw screws into the metal "bridge", shown just below the top lid catch square cutout.

 

Right, but you need to have one of those clip-on sheet metal screw plates, I call them "tinnerman" nuts, but I think just clip-on nut is the general term. I think for a #8 oval head c'sunk screw. Usually available in specialty fasteners at a hardware store.

 

yes, a tinnerman clip-nut that slides over the stationary leg / bracket.
If missing, they have them at ACE Hardware or HomeDepot in the Specialty hardware aisle.

 

Got it- thank you!
