{"product_id":"wilwood-270-11043","title":"Wilwood Front GM G-Body Rotor-Adapter Hub (1980–1987), Confirm H Dimension","description":"\u003cp\u003eFor the specified GM G-Body front conversion, this hub provides an intermediate rotor-plate attachment. A disagreement in the published H dimension prevents treating the listed geometry as settled. Bill Wood’s 1977 founding of Wilwood Engineering began a disc brake design and manufacturing business based in Camarillo, California. The range includes master cylinders, calipers, rotors, brake lines, valves and fittings for motorsport, street-performance and specialized vehicles. Component selection must consider the complete braking arrangement.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 270-11043\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConflicting published dimensions:\u003c\/strong\u003e Dim H: product page 1.950 inch, DS719 1.530 inch.
