A Planted Technology seat bracket for the Oldsmobile Cutlass, 1964 to 1967. Part number SB217.
The A-body Cutlass. It shares a floor with the Buick Skylark and the Pontiac GTO, though each takes its own part number here.
The 442
Four barrel carburettor, four speed gearbox, dual exhausts, which is where the name comes from. Oldsmobile built it as their answer to the GTO and it is the version worth having, particularly the 1966 and 1967 cars with the W-30 package.
The 1997 to 1999 Cutlass is a front wheel drive saloon that shares nothing with this but the badge. If that is what you have, SB149 is your part.
Practical
The bracket picks up the factory mounting points so nothing is cut. On a car worth this much that is the only approach. Label the fixings and store the seats somewhere dry.
Sixty year old American floors are rarely original. Get the carpet up and look before you spend.

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 Oldsmobile Cutlass (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.
