Datsun Roadster Front Wheel Hub Grease Cap
Front replacement wheel grease cap silver colored zinc. NOT a generic Pep Boys "HELP" brand modified for the roadster. Specially tooled for the Datsun Roadster. Not the exact shape but very well done. Tighter than original.
Clean out hole in hub of any built up grease. Best installed straight on working each side gently tapping with a flat drift on the lower lip. Lightly tap on with a plastic hammer until seated.
