I've just assembled my own one after a strip, clean and polish. My first pin I ever took down. It was..interesting. But once we took our time and though things out, along with some good labelling..we managed ok. A couple of times we had to backtrack. But it all went back together and is looking amazing and playing even better. Almost sad it is finished. Now I am going to have to look for another one to do.
Anyways, since mine is fresh in my mind, I can say that I have no idea where that metal guard of yours goes. I didn't see it on mine at all. I thought above the center metal ramp, but that one looks the same size, but is welded on. Not screwed. Do you have one above your ramp? Uploading a pic I got off the net.
It can only be below the playfield, or maybe at the back behind the elevator area, as I didn't strip that.
Anyways, for anyone doing this, it isn't impossible, even for novices. Take it slow, and don't be scared to go backwards and undo stuff to get other stuff fitted properly. Use masking tape to attach each screw to it's part, or screw them back in the holes they came out of. Right ramp first.
The easybreak plastic wasn't so hard. One screw in, swivel it and put in the one screw of the long ramp arm. Then undo that screw, screw in the other one, and swivel it, and put in the other screw. Then install it in place. Does NOT need to be bent at funny angles.
Pics help, but there are enough online to get it sorted. Or ask, and I'll upload some of mine.
Good luck with that pictured part..I have no idea.
