TK2020 Torque King® Premium Quality Complete Gasket Kit for 1973-1979 Ford 4 Speed and Automatic with 31 Spline Female Input Direct Mount New Process NP205 gear drive transfer cases. Features Original Equipment Spec Precision-Thickness Gaskets. Our Torque King® Premium quality Complete Gasket Sets are assembled with highest quality components for your specific NP205 application and are the most complete application specific NP205 Gasket Sets you can buy. Competitive Kits are assembled for generic applications so they rarely include all components required for your exact application, plus these generic kits use parts that do not even come close to meeting original equipment specifications to achieve a lower price when compared to original equipment parts such as those found in Torque King® Premium Gasket/SealKits for your Ford 4x4.

Applications
Tech Note 1: Ford NP205
Ford used a remote (divorced) mount NP205 in the F250 from 1973-1977.5. Direct mount (married) NP205 models were used in 1973-1979 F100/F150, 1977.5-1979 F-250, 1979 F-350, and 1978-1979 Bronco. During the same years, Ford also used the NP203 full time case (1974-1979), Dana 20 (1973-1978 Bronco), and Dana 21 (early 4 speed F100).
Tech Note 2: RTV Sealant
Except for the PTO cover on later production models, NO RTV sealant was used on the NP205 Transfer Case or adapter. All shaft, coupler, and bearing clearances were designed for specific thickness cut paper gaskets. We include a small tube of RTV Sealant if wish to seal the PTO cover with RTV in lieu of a gasket. RTV sealant SHOULD NOT be used to replace any other NP205 gasket, however, you can use a VERY thin film on one side of a gasket to hold it in place during assembly or to fill in gouges in mating surfaces.
