R4 Headlamp casing

[Tomcat]

I am totally confused by where the spring piece fits into the headlamp casing.
Memory has totally gone on this one.
Assistance please. See attached picture

Went on Der Franzose site and found following information.
Even with those I think maybe I am missing a clip or something!!??

OK further research and I have discovered I am a bit missing as shown on page from PR1104.
The clip within box 9 on the left hand side is what I have misplaced. Item is 77 01 200 990. Spring & clip come together.
Anyone have spares they could sell me or anyone have headlight units for sale please?
