{"product_id":"wilwood-270-10439","title":"Wilwood Front Camaro Hub for Vented-Rotor Conversions (1979–1981), A34 Outer Bearing","description":"\u003cp\u003eThe 1979–1981 Camaro application uses an A34 outer-bearing reference with this front adapter hub. Its mounting geometry differs from other Camaro hubs even when their wheel bolt circles match. Disc brake system design and manufacturing are Wilwood Engineering’s focus. Bill Wood founded the Camarillo, California company in 1977; its range spans brake rotors, master cylinders, calipers, fittings, valves and brake lines for motorsport, specialized and street-performance applications. The choice of individual components depends on the complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 270-10439\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel-stud thread:\u003c\/strong\u003e 1\/2-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor mounting arrangement:\u003c\/strong\u003e Adapter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor interface:\u003c\/strong\u003e 5 x 3.88; this is not the wheel bolt circle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible rotor-adapter output interface(s):\u003c\/strong\u003e 6 x 6.25, 8 x 7.00; match the actual adapter and rotor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct-page drawing references (inches):\u003c\/strong\u003e A = 1.584; D = 2.495; H = 1.796; M = 3.150; N = 1.640; P = 3.140; Q = 0.340.
