F355 alternator - top mounting bolt - How do you remove?

I am replacing the alternator on my F355. How do you get to the top mounting bolt. The bolt head and nut are 17mm and I can barely get my fingers to them, but I can't figure out how to get a wrench or socket on them........there are so many things "in the way". I know an alternator replacement can be done from underneath the car. How do you get to the top mounting bolt?......special bent 17mm boxed-end wrenches??


Also, that bottom bolt with the 10mm allan head bolt was a great idea also........NOT.
