A Planted Technology seat bracket for the Plymouth Barracuda, 1970 to 1974. Part number SB221.
The E-body. The 1964 to 1966 first generation takes SB352 and shares nothing but the name.
The Hemi Cuda convertible
Plymouth built fourteen of them across 1970 and 1971, and they are among the most valuable American cars in existence. Even an ordinary 1970 Cuda in good condition is worth real money now.
Which is why nobody should be taking a cutting disc to one of these floors. The bracket picks up the factory mounting points so nothing is cut, and the original seats come out whole. Label the fixings and store them somewhere dry.
Watch for clones
A great many Barracudas have been rebuilt as Cuda tribute cars. If you are working on one and are not certain what the shell actually is, the fender tag and the VIN will tell you, and it matters 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: 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 Plymouth Barracuda. 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.
