A Planted Technology seat bracket for the Nissan and Datsun 260Z and 280Z, mid 1974 to 1978, for cars with angled rear tabs. Part number SB145.1.
Angled rear tabs is the fitment, and you have to look
Datsun used more than one rear mounting arrangement across this period, and there is a separate bracket for cars with flat rear tabs. This is not something you can determine from the year, the model or the chassis number.
Get the carpet up, look at the tabs the seat bolts to, and photograph them. Send us the picture and we will tell you which you have. Five minutes now saves returning a heavy part.
The 260Z and 280Z
These are the later, heavier, more comfortable Z cars, which for years made them the cheap ones. That has changed and they are appreciating alongside the 240Z.
Floors are the Z car problem
Not a formality on one of these. Get right under the carpet and look properly, and be prepared for the answer to be metalwork before seats.
A period trimmed shell suits a Z far better than a modern bucket. 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 280Z (1974.5-1978) *Angled Rear Tabs*, Nissan/Datsun 260Z. 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.
