side indicator

[klumzer]

Could anyone tell me what the exact diameter of the hole of side indicator is on the wheel arch?
They were removed by one of the previous owners and now I would like to restore them.

Thanks in advance.

As I see on the inner side probably 18mm.
Thanks if anyone could verify it...

I verify that the hole is indeed 18mm dia.
For the actual hole location the hole centre is 45mm. on the horizontal to the back vertical edge of the wing panel and 55mm down on the vertical from the top outer edge of the wing panel.
