A Planted Technology seat bracket for the Nissan and Datsun 720 pickup, 1980 to 1986. Part number SB257.
The Hardbody D21 that replaced it takes SB336, so check the year rather than the model name.
The last of the simple Datsun trucks
The 720 is the generation before Nissan dropped the Datsun name entirely, and it is about as simple as a pickup gets: a leaf sprung ladder chassis, a four cylinder engine, and very little else to go wrong. That simplicity is why so many survived long enough to become interesting.
Values on tidy ones have started moving as people rediscover small trucks.
Which changes the approach
The bracket picks up the factory mounting points so nothing is cut, and the original seats come out whole. On a truck that might be restored properly one day, that is worth having.
Practical
Forty year old pickup floors that have carried loads deserve a serious look with the mat up before you spend.
A period trimmed shell suits a truck of this age. 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 Nissan/Datsun 720 Pickup (1980 -1986). 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.
