510/1600 & B110/1200 Retractable Seat Belt Kit – Custom Mounting Brackets Included

Upgrade your Datsun 510/1600 or B110/1200 with this custom-designed retractable seat belt kit, engineered for improved safety and modern convenience. Developed specifically for Datsun models, this kit includes a matched left and right pair of inertia-reel seatbelts and all necessary mounting brackets and hardware for a clean, OEM-style fit.

Designed with attention to comfort and practicality, the kit includes a custom drop link coupling to raise the sash mount to shoulder height — eliminating that annoying “neck rash” common with poorly mounted belts. The rearward mounting position of the reel allows full travel of the front seats with no interference.

This is not a generic belt – it’s a purpose-built safety solution for classic Datsun's, made to Datsport’s strict specifications. Whether restoring your interior, improving safety, or preparing for roadworthy inspection, this kit is a smart and easy upgrade.
