A Planted Technology seat bracket for the Chevrolet Chevelle, 1968 to 1972. Part number SB224.
The 1964 to 1967 cars take SB158.
The 1970 SS 454 LS6
This is the generation with the car at the top of almost everybody’s muscle car list. Chevrolet rated the LS6 at 450 horsepower in 1970, which was the highest figure quoted for any production car that year, and values for a documented one are extraordinary.
Which means paperwork matters as much as condition. If yours is a genuine SS with documentation, treat the interior accordingly.
Reversible, and documented
The bracket picks up the factory mounting points so nothing is cut. Store the original seats and every fixing somewhere dry and label them. On a car at these values an interior that can be put back exactly is worth real money.
Practical
Repair panels are common on these. Get the carpet up and look properly before you spend anything.
Ask us about retro trimmed shells rather than a modern carbon bucket.
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 Chevelle (1968-1972). 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.
