Well, the term CV is too short to search for, so I started this.
Were the factory CV joints made by Lobro, and did they have a date stamp? I know VW Lobros have a date stamp, in the form mm/yy. My CV joints are 951.332.030.00, and say Lobro 23 91. I am guessing this particular joint is original. I will also guess all of the CV's will be original.
The lack of maintenance done on this car is astounding. I hate to say that the wife bought it from an independant Porsche shop, who "maintained" it from the day it arrived in America.
Thanks, and Happy New Year!
