Flexplates are supplied with a ring gear that is securely welded in place and feature dual bolt patterns for flexibility in adapting to multiple transmission style torque converters.All Hays heavy-duty flexplates are zinc-dichromate plated to resist corrosion and are SFI certified under specification 29.1.Features and Benefits:All applications for flexplates are SFI 29.1 CertifiedFits TH350 and TH400Flexplate features Zinc Dichromate Plated finish for superior corrosion resistance and good looksHeavy Duty design utilized thicker than stock steel plate enabling to withstand the stress of high-stall converters and high-RPM enginesDetails:Application: BuickCenter Bore (Register Diameter): 2.486 InchEmission Code: 5Engine Balance: ExternalMaterial: SteelNumber of Teeth: 166SFI Approved: YesSFI Certification: 29.1Warranty: Manufacturer's 90 Day WarrantyApplication Summary:1971-1973 Buick Centurion Base (Liter: 7.5 & Engine(ci): 455 & Cylinder: 8 & Block: V)1970-1972 Buick GS 455 Base GSX (Liter: 7.5 & Engine(ci): 455 & Cylinder: 8 & Block: V)1970 Buick Wildcat Custom (Liter: 7.5 & Engine(ci): 455 & Cylinder: 8 & Block: V)1973-1977 Buick Century Base Luxus Custom (Liter: 7.5, 6.6 & Engine(ci): 455, 403 & Cylinder: 8 & Block: V)1970-1979 Buick Electra 225 Custom 225 Base 225 Limited Limited Custom Park Avenue (Liter: 7.5, 6.6 & Engine(ci): 455, 403 & Cylinder: 8 & Block: V)1970-1979 Buick Estate Wagon Base (Liter: 7.5, 6.6 & Engine(ci): 455, 403 & Cylinder: 8 & Block: V)1970-1978 Buick LeSabre Base Custom Luxus Custom Sport (Liter: 7.5, 6.6 & Engine(ci): 455, 403 & Cylinder: 8 & Block: V)1973-1974 Buick Regal Base (Liter: 7.5 & Engine(ci): 455 & Cylinder: 8 & Block: V)1970-1978 Buick Riviera Base Gran Sport GS SR Sport Lxxv Anniversary Edition (Liter: 7.5, 6.6 & Engine(ci): 455, 403 & Cylinder: 8 & Block: V)1970-1971 Buick Skylark Base Custom (Liter: 7.5 & Engine(ci): 455 & Cylinder: 8 & Block: V)1970 Buick Sportwagon Base (Liter: 7.5 & Engine(ci): 455 & Cylinder: 8 & Block: V)
