- Hummm. After owning my white 359 for several years i haven't had any cracks or other problems. But its identification lable say fiberfab. And has the Ca. Spcn smog label too. And better too as it has porsche guages, no hood pins, better mirrors. It seems to attract a lot more attention than the porch 356 because nobody knows what they are but that's just my opinion I Luv It. all though I don't use it much.
