R129 front indicators

[Stegel]

The front nearside (clear) indicator on my 97 SL500 periodically worked its way forward by a few mm every few weeks, and has now flung itself onto the road, at speed, and is lost. I guessed this was due to it being an ill-fitting pattern part, so decided I would replace it with a genuine MB article.

Surprisingly, given generally good parts availability, this part is longer supplied by MB (I checked with two dealers just to be sure).

Before I buy a no-name pattern off eBay, has anyone got any advice regarding a good supplier - I have spotted some Magnetti Marelli items at twice the price of the cheapos; did MM supply MB?

(And before any 1-5 barge threadists make any suggestions, I'm not interested in ginger-ing the car).

Thanks
