Looks as though everything is there to me.
The shorter red line (near the battery) is only there to allow for access to the battery retainer bolts.
The other space is always empty from memory, although I seem to remember a few A2s having it filled with more foam!
As long as you got the jack, wheel brace, security nut, spanner, screwdriver, hub-hook, spinner, tyre gunk and compressor, you've got it all.
The other spaces at the back are for the navigation unit and diversity aerial box.
