Measure the spring-eye shell and bolt sleeve before ordering W72133. This is a rear-position spring-eye bushing kit with two shell bushings and two tubes, not a complete collection of every bushing under the truck. Whiteline lists a 31.8 mm shell outside diameter and 19 × 14.3 × 76 mm tubes. Match those dimensions to the spring and mounting hardware on your F-100.
The proposed classic application is limited to the Ford F-100 years and trim/engine combinations shown in the attached source rows. The maker’s rear fitting position and the original spring-eye arrangement must agree with the truck. Modified leaf springs deserve a measurement, not a hopeful year lookup.
The black synthetic-elastomer bushings replace a wear item at the spring eye. Whiteline estimates three hours and describes the job as straightforward with the right specialist tools and knowledge. Use the vehicle workshop manual for safe spring support, bushing removal and fastener torque; a wheel alignment is not listed as required.
