A Planted Technology driver side seat bracket for the Chevrolet Corvette on the C3 chassis, 1968 to 1982. Part number SB267.
The fitment warning is the important part
Planted state that this may not fit every C3. Fourteen years of production is an extraordinarily long run and Chevrolet changed a great deal across it, so the year alone will not tell you.
Before you order, get the carpet up, photograph what is under the seat, and send it to us. We will check it against the bracket and tell you honestly whether it suits your car. On a C3 that five minutes is worth it, because the alternative is returning an awkward, heavy part.
The early cars are the valuable ones
The 1968 to 1972 chrome bumper cars, and particularly the big block and LT-1 versions, are worth a great deal more than the later ones. Values fall away sharply after 1973.
The bracket picks up the factory mounting points so nothing is cut, and the fibreglass body means you would not want to be improvising anything anyway.
Driver side only. Ask us about retro trimmed shells.
Have you written anything about this exact product?
Yes, we have covered this exact product: Planted Technology Chevrolet Sub-Frames: Ready For The 2025 Racing Season. 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 Chevrolet Corvette [C3 Chassis] (1968-1982) - Driver / Left *May not fit all C3 Chassis, see online diagram. 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.
