Designed as a direct replacement for the factory rear spring center mount plate, this heavy-duty stamped steel component securely anchors the transverse rear leaf spring to the differential cover, maintaining proper suspension geometry and drivetrain stability. Over time, the original mount plate can become bent, cracked, or corroded from years of service, high-performance driving, or suspension repairs, resulting in poor spring alignment, unwanted movement, and compromised handling. Replacing the mount plate restores the factory mounting integrity and dependable suspension performance. This reproduction features the correct 1\/2-inch bolt holes used on 1977-1979 applications and replaces GM part number 457977.\u003c\/p\u003e\n\u003cp\u003eManufactured in the USA to meet or exceed OEM specifications, this restoration-quality rear spring mount plate is precision stamped from heavy-duty steel for superior strength and durability. It installs using the factory mounting locations without modification and is engineered to provide a secure attachment point for the rear leaf spring. Whether you're replacing a damaged original, rebuilding your rear suspension, or completing a concours-quality restoration, this mount plate delivers the factory-style fit, function, and reliability Corvette enthusiasts expect.\u003c\/p\u003e\n\u003cp\u003eFeatures \u0026amp; Benefits:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDirect replacement rear spring mount plate\u003c\/li\u003e\n\u003cli\u003eDesigned specifically for 1977-1979 Corvette models\u003c\/li\u003e\n\u003cli\u003eSecures the rear leaf spring to the differential cover\u003c\/li\u003e\n\u003cli\u003eCorrect 1\/2-inch spring mount bolt holesRestores proper rear suspension alignment\u003c\/li\u003e\n\u003cli\u003eHelps maintain factory ride and handling characteristics\u003c\/li\u003e\n\u003cli\u003eHeavy-duty stamped steel construction\u003c\/li\u003e\n\u003cli\u003eManufactured to meet or exceed OEM specifications\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003cli\u003eDirect replacement installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eProduct Details:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eProduct Type: Rear Spring Mount Plate\u003c\/li\u003e\n\u003cli\u003eLocation: Rear Differential \/ Leaf Spring Center Mount\u003c\/li\u003e\n\u003cli\u003eMaterial: Heavy-Duty Stamped Steel\u003c\/li\u003e\n\u003cli\u003eBolt Hole Size: 1\/2 Inch\u003c\/li\u003e\n\u003cli\u003eReplaces GM Part Number: 457977\u003c\/li\u003e\n\u003cli\u003eOEM-Style Replacement\u003c\/li\u003e\n\u003cli\u003eDirect Bolt-On Installation\u003c\/li\u003e\n\u003cli\u003eRestoration-Quality Component\u003c\/li\u003e\n\u003cli\u003eFactory-Correct Design\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFitment:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1977 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e1978 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003e1979 Chevrolet Corvette\u003c\/li\u003e\n\u003cli\u003eFits C3 Corvette Coupe and Convertible models\u003c\/li\u003e\n\u003cli\u003eDesigned for factory rear transverse leaf spring suspension\u003c\/li\u003e\n\u003cli\u003eCompatible with original and OEM-style heavy-duty differential covers and rear spring hardware\u003c\/li\u003e\n\u003cli\u003eVerify your rear spring mounting hardware and bolt size before ordering to ensure proper fitment.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CA","offers":[{"title":"Default Title","offer_id":53189226529133,"sku":"A330973","price":38.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0032\/6683\/8574\/files\/30973-1.png?v=1783030215","url":"https:\/\/www.westcoastcorvette.com\/products\/c3-1977-1979-chevrolet-corvette-rear-spring-mount-plate-ca-30973","provider":"WestCoastCorvette.com","version":"1.0","type":"link"}
