Using a Phillips screwdriver, unscrew the screws securing the storage shelf:
to the radio mounting panel (one screw),…
...side panel upholstery (two screws)…
Original source is on the resource VAZbook
... and to the front shield bracket (one screw).
We lower the right end of the shelf.
We remove the shelf tenon from the radio mounting panel..
…and remove the shelf.
We install the shelf in the reverse order. First, it is convenient to screw in all the screws, and then tighten them.
