Where do the Slide Fixes go? Images?

As the title says. I think I figured out where slide fix 2 goes by the shape of it but can't work out slide fix 1.

Are there any images of where these fixes go?

I'd like to make a full assembly guide with images to help everyone out but I don't even know where these fixes go or the real purpose at the moment.

Cheers for all your great work!
