Product Overview
The Fel-Pro 13365 is a round, metal drive axle shaft flange gasket specifically designed for a range of Cadillac models, including the 1950‑1964 Series 60 Fleetwood and the 1958‑1958 Series 70 Eldorado. Constructed from high‑grade steel with a proprietary coating, the gasket resists corrosion, heat, and vibration while maintaining a tight seal between the axle flange and housing.
