A Planted Technology seat bracket for the Nissan and Datsun 240Z, 1970 to mid 1974. Part number SB138.
We list the 240Z twice, this and SB138-1. Either page gets you a 240Z bracket, so order from whichever one found you and we will confirm against your chassis number if you want certainty.
The car that changed how America saw Japanese cars
Independent suspension all round, an overhead cam straight six, and a price that undercut everything it drove like. Datsun sold enormous numbers and the 240Z is now the one collectors want out of the whole S30 run.
Values reflect that, and a matching numbers early car is worth serious money.
Which decides the approach
The bracket picks up the factory mounting points so nothing is cut. Store the original seats and every fixing somewhere dry and label them.
Rust is the standing S30 problem
Floors, the areas round the seat mounting and the frame rails. Get right under the carpet and look properly before you spend anything, and be prepared for the answer to be metalwork first.
Ask us about retro trimmed shells, which suit the period far better than a modern bucket.
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 240Z (1970-1974.5). 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.
