For a 126, you do not have to convert the wipers too. In my opinion though, the euros look a helluva a lot better because they lay at the bottom edge of the headlight out of the way and don't stick up with 2 right angles like the US ones do. Every once in a while some wiper motors will come up on german ebay. You wouldn't believe the crap I've gotten from there!
