The spiral in lower grey is almost certainly the top of a barbed wire fence, so it would have to be rotates so its horizontal

This is how I got 1029-LY and 7676-AL to fit together

I think you're right about those fitting together, lookin at the barbed wire spiral

if you rotated it counter clockwise and pushed it over so theres a gap where his head should be, i think thats the final picture
