Shiny paint causes stress.
I recently bought a set of Howard's lifters that came in a plastic clamshell package just like those.I truly believe Torqueflite got repackaged 5003's because mine purchased approx. 1 1/2 years earlier from Hughes were packaged differently (post #4).
I have had a set of Hughes 5003s for years and years but they came from cleaning out an older guy's garage so I don't know if they're new or used. They are packaged in a custom-sized cardboard box with thin dividers (IIRC).
