I support Pelicanparts all the way. I own a 72 911. That site has taught me everything to keep my Porsche running and away from those greedy mechanics. Wayne ( the owner) wrote a great book, 101 Projects for your Porsche, which made it very easy to work on these classic car. Great group of people on the site who are very eager to help. The site is FREE! There are technical articles for anyone to look at.
P.S. I wish someone here could write a 101 projects books for mercedes, ie for W107, 126, etc chassis
