A Planted Technology seat bracket for the Buick Skylark, 1964 to 1967. Part number SB218.
The A-body Skylark, and the generation that gave us the Gran Sport. It shares a floor with a family of General Motors cars of the period, including the Oldsmobile Cutlass and the Pontiac GTO, though each takes its own part number here.
Buick did things differently
The Gran Sport used Buick’s own nailhead V8 rather than a Chevrolet engine, which is why parts hunting on one of these is its own discipline and why the cars have a following separate from the more obvious muscle cars.
Reversible on a sixty year old car
The bracket picks up the factory mounting points so the original seats come out whole and nothing is cut. On a car of this age that is the difference between a modification and damage.
Practical
Lift the carpet and look properly. American floors of this age are rarely original and repair panels are common, and a bracket can only feed seat load into sound structure.
Ask us about retro trimmed shells, which suit the period. 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 Buick Skylark. 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.
