I'm replacing the alternator on my friends 2002 E320. Went to AutoZone and ordered a reman unit. Took it to my friends, pulled the old one and the rear connections are set up slightly different, the Autozone unit will not allow the strange shaped connector from the car to fit snug against the screw/bolt connection. Naturally I curse Autozone's name assuming they gave me the wrong part.
The alternator on the left is the Re-manufactured, Right is Original from car.

The one on the left looks exactly like the one FastLane brings up for the car. I even typed in the part number on the side of original alternator and it brought up a listing for the one on the left....

After doing quite a bit of searching, I found that an alternator for a C-class looks just like the one off my friends E320...

I'm sure I could modify the connector from the car to get it to fit the new alternator. Should I do that or try ordering the Alternator from the C-class?

The part number off the origional Alternator is: 011 154 62 02

Any help would be greatly appreciated, I'm stumped here....
