A Planted Technology seat bracket for the Datsun 510, 1968 to 1974. Part number SB124.
The 510 is the car that established Datsun as a serious manufacturer. Independent rear suspension and an overhead cam engine in a cheap saloon, at a time when nobody else was offering that, and a Trans-Am championship to prove the point.
Which is why they are historic racing cars now
Most 510s being built today are being built to compete, not to commute. That changes the conversation: if you are running in a historic class, tell us the class before you order anything, because those rulebooks are frequently specific about seats and mounting and getting it wrong is an expensive way to find out.
The floor is the real question
Fifty five year old Datsun floorpans are not famous for surviving. This is not a formality on a 510: get the carpet up and look properly at the metal round every mounting point, and be prepared for the answer to be that it needs metalwork first.
Practical
The bracket picks up the factory mounting points, so nothing is cut on a car that is now genuinely valuable.
Handed, so order twice for a pair.
Have you written anything about this exact product?
Yes, we have covered this exact product: Lexus Planted Technology Frames Updated For 2026, and Customer Car: Subaru Impreza With Corbeau RRS Seats and Planted Technology Brackets. That is first-hand coverage from our own builds and showroom, not brochure copy.
Will this fit my car?
This frame is made for the Datsun 510 (1968-1974). Chassis code and years matter more than the badge, as floor pans change between generations, so if your car sits near a changeover year, send us the registration and we will confirm before you order.
Which seats does it take?
Check the bolt pattern in the specification against your seat. The Compatible seats tab above lists what bolts straight on. If your seat is not listed, tell us what you run and we will confirm the fit.
Do I keep fore-and-aft adjustment?
Only with a sliding runner between the frame and the seat, which is a separate part on Planted frames. If more than one person drives the car, budget for the runner. Our guide to sliding runners explains the options and widths.
Is this for the driver or passenger side?
Both sides are available on this listing, pick driver or passenger side at the point of order (sides listed are for right-hand-drive cars). Left-hand-drive car? Ask us, as the sides swap over and availability varies by model.
