A small update: You probably know that the US headlamp wiper arms, motors, and motor brackets are different then the euro ones. The holes in the trim strips below the headlamps are different too.
I bought a set of euro wiper motors, only to find they were totally rusty inside and totally dead. However, after taking the euro and US wiper motors apart I found that the only differences were the shaft coming out of the front (US is longer) and the gear which drives a small rack to spin the shaft (US has a shorter sweep). I was able to install the euro gears into my US motors, creating a hybrid that allows me to use the US brackets and trim strips, but still have the correct sweep. The wiper arms off of a late W124 complete the package.
Much better looking, and functional
