Planted Technology seat brackets for the Pontiac Firebird Trans Am. Part number SB140-4964.
The same bracket as our 1982 to 1992 Firebird listing under SB140, listed here under the Trans Am name because that is what a great many owners call their car and search for.
Send us the year, because Trans Am is a trim level
Pontiac applied the name across most of the Firebird’s life, from 1969 to 2002, so it does not identify a generation on its own. The generations take genuinely different parts: 1967 to 1969 is SB219, 1970 to 1974 is SB220, and from 1993 the Firebird shares with the Camaro under SB059.
Tell us the year and the engine and we will name the part. We are adding the year data to this listing.
Practical
Third and fourth generation Firebirds rust and few were cherished. Get the carpet up and look at the metal round the mounting points before you spend anything.
Handed, so order twice for a pair.
