w123 Euro lites

[mybenz123]

Hello all.

I just scored some euro lites for my w123 wagon.
See attached pic.
I bought them on ebay for $150 including shipping.
They are made by hella.

They seem in pretty good condition for their age but
have some issues.

The driver side one seems to be in the worst condition.
There is some corrosion on the bracket that holds the
vacuum adjust element and the headlite sockets.
Also the plastic adjustment parts are brittle and some
broke already.
This seems to be because at one point the glass has been
replaced with glass from bosh and the seal doesn't do its
job very well.

The passenger side has new head and fog lites but one of
the plastic adjustment pieces broke.

My main concern are the plastic adjustment doodats,
as said before they are brittle and ready to break, if not
broken already.
I glued them, but don't think this will last long.

I have an original parts book for my wagon, and the
replacement parts available are.
Headlite, foglite, glass, rubber seal and some more
stuff.
BUT not the plastic doodats for the adjustment.

My question is:
Does anyone know whether they are still available?

I hate to have to replace the whole assembly just for
those plastic pieces.

Any info welcomed.

Louis.
