Here is a rare original 94 red part ... :D

Mines a spring clip that slides over the plastic to take the screw like Rob describes,you might be able to get some from an automotive supplier for a few pence.

Cheers men.

You're welcome ...

Here's the clip thingy. It's the right bit as the description on the packet confirms. I think the rivnut type where on the 851.

Rgds, Rob

We use clips like this in rack mounts for computers.

Is this the same thing?

Mike,

Those are the same as the mirror mounts and the upper front side panel fixing. M6 captive nuts are used in 6 places on the headlight frame, 3 each side.

Still looking for the 4mm clips, only 656,000 hits in Google!
