Dose anyone know a source for the two bolts that hold the alternator bracket to the side of my 3B ? They have a small head for such a large diameter bolt and a shoulder to match the thickness of the mount. I can't find them in my 3b factory manual but I'm pretty sure their a special factory bolt. I tried to replace one with a standard metric bolt , but it has no shoulder and a 17 mm head that wont fit thru the mount. the factory bolt is a 14 mm head , I believe. Any help guys???
