I also want to secure my battery properly so had a look at RealOEM but some things are not clear:

I have only parts 6 and 4 from this diagram (plus a bettery obviously).
Part 4 sits below part 6 and plugs a hole in the floor which means that despite serving no purpose with a modern battery I will keep it where it is.
But what is the point of the strap (no 13) given that the tray (no 6) is not fixed into the wheel well (or should it be fixed in somehow)?
Also where does the threaded of part no 7 go? I can't see anywhere in my tray or in the floor of the well where this would thread in?
Thanks in advance.
