I need a new rubber plug for one of the holes in the metalwork near the battery.

It's the type that is sort of finger-shaped, with a split at the base, and fits the circular holes in the metalwork, having a pair of small cut outs in its rim flange to aid fitting.

Closest picture I have just now is this one, which shows the position of the missing one, but there's about four or so in that area altogether.

Unfortunately, none is really easy enough to extract to see if there's a part number, without risking losing it (ahem) into the hole. As usual with things I need, it just doesn't seem to be in PET.

Any ideas?

 

Just in case anyone else needs this, I managed to remove another one - the part number is 999 703 476 40.

Interestingly, when you search for this in PET, the relevant page (107) has two item #16s - one is the grommet in question.
