Jim,
I don't know anything about the quality of Uro Parts.
BUT, Nate and I swapped out the turnsignal/wiper switch in my 300SD (126). It was dead simple, once we understood it.
Pull the steering wheel (one nut);
Pull the switch out (2 screws and two plugs at the end of wires that go through the column jacket and under the kick panel above the pedals); The wires run through the top jacket of the column, which only extends down to the dash, and then ends;
Put the new switch in, connect the plugs, put in the two screws;
Reinstall the steering wheel;
Take the wheel off again, adjust it so that it is lined up properly, then reinstall it.
We find PLENTY of 126s in P-a-P yards, with NEVER any missing turn signal switch. So get one there, instead of paying $50. The time spent in the yard will also give you a good lesson in how the switch comes out without causing damage.

Anyone tried the Uro Parts Blower Motor for the W123? Remember for a while those motors became impossible to get and suddenly went over $500 new? Now I see they are back as Uro Parts new around $90 at the usual places, autohausaz.com, rmeuropean.com, ebay.com, etc. I just ordered one for my 84 300D...hope they draw less amperage than the original. Will let you know how it works out if anyone is interested. Also ordered a new combo switch (turn signal/wiper/etc) same brand Uro Parts $50. My original switch is worn out. I hope that is not a hard job to swap out. Anyone done this job? Advice appreciated.
