Condition: NOS Description: FL-1 Autolite Oil Filter Application: Mustang / Shelby Quick Part #: FL-1 Part Number: C1AZ-6731-A Date Code: 4-0568 (May 1968) Jack’s Comments: This new old stock FL-1 oil filter with box in original condition with minor box/shelf wear. When my friends uncle died (God rest his sole) we found two Autolite filters when going through his stuffed garage way in the back of a cabinet that looked like it hadn't been opened since 1970. Two filters are available, both have the same date code. Boxes were dated 1966. Related Pictures: More Info or Links: Production line oil filters were painted Ford Corporate Blue. I know its hard to paint over a NOS filter but if you’re going for any concours trailered classes you really need to do it. ~Jack Shipping US: UPS Ground Shipping NON-US: Call or email for an exact shipping quote
