The Seatbelt Planet 1968-1973 Datsun 510, Rear Driver & Passenger Seat Belt Kit, sold by Vintage Car Radio, is a practical and worthwhile addition that brings the rear bench of these classic compact sedans and wagons up to modern safety expectations.

While the Datsun 510 is best remembered for its sharp handling and enthusiastic driving character up front, the rear seat played an important everyday role. Many owners used these cars as practical family vehicles or versatile daily drivers. The rear bench offered decent space for two adults or three on shorter trips, making the 510 more than just a solo sports sedan.

It was often pressed into service for road trips, carrying friends to meets, or family errands. However, the original rear restraint systems were minimal at best. Most examples came with basic lap belts that have long since deteriorated, faded, or been removed entirely. This left the rear passengers with little protection, creating a noticeable gap in an otherwise capable and beloved car.

This Seatbelt Planet kit specifically targets the rear outboard positions with a pair of 3-point lap-and-shoulder belts designed for the 510’s rear bench layout. The high-strength webbing is fade-resistant and available in a range of colors and textures that complement original or restored interiors. The buckles are solid all-metal push-button designs with chrome plating, providing a crisp, positive click and easy release that feels appropriate for the car’s era. Chrome-plated hardware and anchors are selected to integrate cleanly with the 510’s simple rear interior trim, maintaining the car’s clean, functional aesthetic.

One of the strengths of this kit is its balance. It adds meaningful modern protection without introducing bulky retractors or heavy mechanisms that would feel out of place in the 510’s lightweight cabin. The belts remain relatively unobtrusive when not in use, preserving the rear bench’s open and practical feel.

Installation is straightforward and sympathetic to the car’s construction. The kit includes all necessary mounting hardware and is engineered to work with the existing rear floor points in most cases, requiring minimal modification. The adjustable straps ensure a secure, comfortable fit for different body sizes while maintaining the rear bench’s usable legroom and accessibility.

Seatbelt Planet builds these kits to exceed FMVSS 209 and 302 standards, offering solid tensile strength, durability, and flame resistance. For 510 owners who regularly carry passengers — whether family members, friends heading to a car meet, or kids on weekend adventures — this upgrade makes the rear seat genuinely usable again instead of an area of concern.

Vintage Car Radio provides reliable shipping and support for this kit, making the rear-seat refresh easy to accomplish.

In summary, the Seatbelt Planet 1968-1973 Datsun 510 Rear Driver & Passenger Seat Belt Kit is a sensible, high-value improvement that completes the car’s safety profile. It respects the 510’s reputation for practicality and everyday usefulness while adding modern three-point protection to the rear bench.
