A Planted Technology seat bracket for the Mazda B Series truck, fourth generation, two door, 1985 to 1998. Part number SB335.
Two door is the qualifier, so check what you have. The fifth generation takes SB391.
Mazda built these, and then Ford sold them too
The badge engineering ran both ways over the years, which is why B Series and Ranger parts cross reference so widely. For this generation Mazda built the truck and Ford sold a version of it, and then the arrangement reversed for the fifth generation.
If you are cross referencing parts, search both names. If you are not sure what yours actually is, send us the chassis number.
Why these get seated
Almost always because the original has collapsed. A thirty year old working pickup seat has usually lost every bit of shape it had, and a competition shell on a bolt in bracket is a straight upgrade rather than a motorsport modification.
If the truck still works, ask us about neoprene trimmed shells rather than velour.
Get the mat up and check the floor before you spend.

Will this fit my car?
This frame is made for the 2 Door] (1985-1998), Mazda B Series Truck [4th Generation. 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.
