HB Headlamp Surround Dimensions

[Kraken]

Does anybody have the dimensions (preferably a technical drawing) of the surrounds/mounts for the HB headlamps?

The part I am meaning is part of the steel wings:



And it is not part of the fibreglass wings:



A technical drawing would be great, but even a decent photograph with some of the dimensions would help.

Thanks, - Callum
