A Planted Technology seat bracket for the Chevrolet Chevelle, 1964 to 1967. Part number SB158.
The 1968 to 1972 cars take SB224.
The first generation is the underrated one
Everybody chases the 1970 LS6, so the earlier cars have always been cheaper. The 1965 Z16 SS 396 is the rare one here, with around 200 built, and it is the car that established the Chevelle as a serious muscle car in the first place.
It shares a floor with a family of General Motors A-body cars of the period, including the Buick Skylark and the Oldsmobile Cutlass, though each takes its own part number here.
Reversible on a car worth this much
The bracket picks up the factory mounting points so nothing is cut. Store the original seats and every fixing somewhere dry and label them.
Practical
Sixty years old and repair panels are common. Get the carpet up and look before you spend.
Ask us about retro trimmed shells rather than a modern 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 (1964-1967). 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.
