Dakar Headlight - how to attach/the housing no longer works

[Inglsman]

Hi

I've taken the headlight out and the goodies that hold the adjustment screws have disintegrated (plastic things). The headlight never really pointed in the right direction anyway, and adjustment was impossible without seriously strong fingers..

So now I have a headlight cable tied onto the frame itself (ie set back from the front of the screen) - looks a bit snarks, but is set the best it's ever been (previously I had a pretty good view of the stars).

So, has anyone got a better idea of how to attach the headlight?

Or

are those plastic things readily available? [the screws that adjust the light direction is set into the light fram using plastic inserts into the frame of the headlight]

heck, I hope that makes sense...
