Finding the best places to buy parts for a 1979 Trans Am takes more than a quick Google search and a credit card. The 1979 model year was one of the highest-production years for the second-generation Trans Am, which means the aftermarket took notice early and has had decades to produce reproduction parts ranging from factory-accurate to barely acceptable. Knowing which suppliers to trust, and which sources to use for original pieces, makes a meaningful difference in the quality of a finished restoration.
Before you order anything, confirm which engine your car has. The 1979 Trans Am came with three options: the standard 403ci Oldsmobile V8, the 400ci W72 performance option (the genuine "T/A 6.6"), and an uncommon 301ci Pontiac V8 available as a credit option. The 400ci W72 was not certified for California emissions, so cars built for California buyers received the 403. Part numbers diverge significantly between these three engines, and ordering the wrong carburetor kit or intake gasket set wastes money fast.
Where to Find 1979 Trans Am Parts: The Short Answer
For reproduction body panels, weatherstripping, exterior trim, interior components, and most mechanical hardware, two dedicated Firebird restoration suppliers cover the majority of what any restoration requires: Classic Industries and Eckler's. Both maintain detailed, year-specific catalogs for second-generation Firebirds and Trans Ams.
For original GM parts still in the box, eBay is the single largest marketplace. Expect to pay a premium over reproduction pricing for genuine NOS pieces. For used pulled parts, Facebook Marketplace and specialty salvage yards are viable if you can verify condition and confirm correct application before committing.
For technical guidance on exact part numbers and option codes before you spend anything, the Pontiac Oakland Club International (POCI) is the authoritative club resource. Their registry, technical advisors, and member network have saved more restoration budgets than any catalog.
Dedicated Firebird Restoration Suppliers
This is where most 1979 Trans Am restorations begin, and with good reason. These suppliers built their businesses around second-gen Firebird and Trans Am inventory and have worked through the year-specific fitment problems so you do not have to.
Classic Industries
Classic Industries carries one of the widest reproduction catalogs for second-gen Firebirds available anywhere. Their inventory covers body sheetmetal, hood and body decals, T-top seals, full weatherstripping sets, carpet, interior door panels, dash components, and exterior emblems. Their online catalog filters by year, which cuts the risk of ordering a part correct for a 1977 but wrong for a 1979 application. For a 1979 Trans Am specifically, they stock the correct Firebird hood bird decal in the appropriate colorways for each exterior finish, and their trim coverage extends to items that are genuinely difficult to find elsewhere.
Eckler's
Eckler's has been supplying classic car restorations for decades, and their Firebird section is well-stocked for second-gen applications. They carry comparable categories to Classic Industries, and checking both suppliers before placing an order is worth the extra few minutes because pricing and in-stock availability differ item by item. Eckler's tends to have strong coverage of mechanical components alongside cosmetic restoration parts, which is useful when you are sourcing brake hardware, cooling system components, and suspension parts in the same order.
NOS, Used, and Salvage Sources
Reproduction parts solve most problems but not all of them. Some components have never been reproduced, and for a numbers-matching build or concours-level restoration, original parts are the only acceptable answer.
eBay
eBay remains the largest single marketplace for NOS and used second-gen Firebird parts. Search strategy matters here. Use specific GM part numbers when you have them, and run both "1979 Firebird" and "1979 Trans Am" as separate queries because sellers do not always list under both names. Watch for listings that use photographs from a different model year. Exterior trim changed between 1977 and 1979 in ways that matter, and a part that looks similar in a photo may not install correctly or match the surrounding panels on your car.
Facebook Groups and Online Forums
Several large Facebook groups are dedicated to second-gen Firebirds, and parts transactions happen regularly inside them. Sellers in these communities tend to know their cars better than the average eBay lister. PY Online and similar Pontiac-focused forums carry active classified sections where parts move year-round. These communities are also useful for confirming whether a listed part is actually correct for a 1979 application before money changes hands.
Specialty Salvage Yards
General-purpose salvage yards rarely catalog second-gen Firebird inventory accurately. Specialty yards focused on muscle cars and classic GM vehicles are a better use of your time and fuel. Call ahead with your specific part number and confirm the year of the donor car before making the trip. Second-gen Trans Am shells are harder to find in yards than they were twenty years ago, but they still surface, especially in the Southeast and Midwest.
Pontiac Club Networks and Swap Meets
The Pontiac Oakland Club International hosts their annual Pontiac-Oakland Nationals, which draws vendors, restorers, and parts sellers from across the country. Transactions at this event often involve sellers who can document exactly which car a part came from, which is valuable for anything going on a concours or judged build. Regional POCI chapters hold smaller swap meets throughout the year at lower price points, though inventory quality varies more.
If you are hunting for a hard-to-source trim piece or need confirmation that a part is year-correct before buying, the POCI technical advisor network is a resource no online catalog can replace. This is especially true for option-specific components tied to packages like the Y84 Special Edition (the black-and-gold exterior combination) or the WS6 handling package.
Engine-Specific Sourcing for the 1979 Trans Am
The three-engine lineup creates three different sourcing paths, and this is where many restorers lose time and money.
The 403ci Olds V8 is an Oldsmobile engine, not a Pontiac. Carburetor components, intake manifold gaskets, and many internal parts come from Oldsmobile-focused suppliers as much as from Pontiac sources. If your car has the 403, bookmark suppliers that specialize in Olds engines alongside your usual Pontiac sources.
The 400ci W72 is a Pontiac engine with solid aftermarket support. Demand from performance enthusiasts keeps the supply of rebuild kits, carburetor parts, and go-fast components reasonable.
The 301ci credit-option engine has thinner parts availability than either the 400 or 403. Budget more sourcing time if your car has the 301, and expect to pay more for some items.
What to Confirm Before You Order
Pull your cowl tag or broadcast sheet and confirm your trim level and option codes before ordering interior components. The standard 1979 Trans Am seat was the Deluxe Bucket in vinyl. The only factory leather seat in the entire second-generation Firebird line appeared in the 1979 10th Anniversary Trans Am (option code Y89), finished in Platinum Silver Metallic with a silver and charcoal interior. Approximately 7,500 Y89 units were produced. If your car is not a Y89, you are restoring vinyl seats, regardless of what a previous owner installed or claimed.
Confirm your exterior color before ordering decals. The Y84 Special Edition package used specific gold bird graphics designed for its black exterior, and those graphics are not interchangeable with standard-color cars. Ordering the wrong decal set is a preventable mistake.
Verify whether a part is year-specific or covers a range. Many suppliers list items as fitting "1977-1981," but 1979 saw specific trim and component changes that affect fitment and appearance. When in doubt, order by part number rather than by year range.
