Printed page 4-30, group 4.163 (PDF 36), identifies a 3/32-inch-thick driven clutch plate specifically for the 1966 Corvette 427 under Powerglide. Adjacent group 4.164 also lists clutch assembly 3901124 for 1966–67 Corvette 427 applications. This legacy URL formerly labeled the application L36/390 hp in convertible form. Those engine-rating and body-specific claims are not established by the cited service pages and are no longer asserted here. Chevrolet's October 7, 1965 AMA sheet (1966 kit PDF 83) and December 1965 Power Teams sheet (PDF 59) list L36 with four-speed only. Hemmings identifies a late L36/390-hp Powerglide pairing, but that is secondary historical identification, not the scope of the manufacturer service evidence. No exact introduction date, body allocation or production count is asserted.
