There is no manufacturer-published interchange table for these cars. Owners have worked around that for years with a folk method — calling a parts counter and claiming to own two different vehicles to see whether the same number comes up. This guide replaces the guesswork with the actual platform structure.
One platform, five nameplates
From 1989 to 1994, the Geo Metro and its siblings were the same vehicle: the second-generation Suzuki Cultus. Most North American cars were built at CAMI Automotive in Ingersoll, Ontario — a General Motors and Suzuki joint venture — and badged for whichever market and brand they were destined for.
| Badge | Market |
|---|---|
| Geo Metro | United States (Chevrolet Metro from 1998) |
| Suzuki Swift | North America and global |
| Suzuki Cultus | Japan and various markets |
| Pontiac Firefly | Canada |
| Holden Barina | Australia |
The practical upshot: a door seal, a window sweep, a handle bezel or a piece of glass trim for a 1992 Metro is, in the vast majority of cases, the same physical part as one for a 1992 Swift or Firefly of the same body style. That's why a single reproduction can serve five nameplates — and why it's worth checking listings under all five names when hunting new-old-stock.
Chassis codes — the thing to actually search by
| Code | Meaning |
|---|---|
| SF310 | 1.0 litre G10 three-cylinder |
| SF413 | 1.3 litre G13 four-cylinder |
Body, trim, glass and sealing parts are generally shared between SF310 and SF413. Engine, transmission and related drivetrain parts are not. When searching a factory parts catalogue, the chassis code plus model year gets you far closer than any badge name will.
The four splits that actually matter
1. The 1992 facelift
VERIFY BEFORE ORDERINGThe cars received a facelift for 1992 affecting fascias, lighting and interior. Sealing profiles are widely believed to carry across it, but that's an assumption rather than a documented fact — and this site doesn't publish assumptions as fitment. Treat pre-1992 and 1992-onward as potentially different for anything touching the front end or interior until you've confirmed the part number.
2. Body style
WELL ESTABLISHEDThree-door, five-door and convertible. Door seals are shared across all three, which is unusually generous. Quarter glass, roof and rear body parts are not — a 3-door quarter window seal will not serve a 5-door, and this trips people up buying used because the cars look similar in photographs.
3. Convertible model years
The convertible ran through 1993; there is no 1994 convertible. Anything specific to the folding top is its own parts universe.
4. The Chevrolet Sprint is a different car
WELL ESTABLISHEDThis is the single most expensive mistake available in this hobby. The 1985–1988 Chevrolet Sprint is the Mk1 Cultus — an earlier body. Drivetrain components frequently interchange, so people assume the rest does too. Body panels, glass and weatherstripping do not. If a seller lists a seal as fitting "Sprint/Metro," ask which years before you buy.
REGIONAL DIFFERENCES ARE REAL
Canadian, European and Pacific-market catalogues sometimes list different part numbers for what appears to be the same component. Those differences are genuine — lighting and market regulations drove some of them — and they're exactly why fitment claims here get verified against multiple regional catalogues before publication rather than assumed from one.
How to verify a part yourself
- Identify your chassis code and year. SF310 or SF413, plus model year and body style. This is your search key.
- Look the part up in an online factory catalogue. Several sites host Suzuki parts catalogues with exploded diagrams searchable by chassis code. Find the figure, find the callout, note the number.
- Confirm it in a second catalogue. If two independent sources agree on the number, you can order against it with confidence. If they disagree, you've found a regional or model-year split worth investigating.
- Cross-check the GM number if relevant. Some components carry General Motors part numbers alongside Suzuki ones, which opens up different supplier stock.
- Search all five badge names. Stock listed under "Suzuki Swift" is invisible to someone searching "Geo Metro," and that's frequently where the remaining supply is sitting.
Frequently asked
Are Geo Metro and Suzuki Swift parts interchangeable?
For 1989–1994, largely yes — they're the same platform with different badges. Body, glass, trim and sealing parts generally cross between badges of the same body style and year. Verify the specific part number before ordering, especially across the 1992 facelift.
Will Chevy Sprint parts fit my Metro?
Some drivetrain parts, yes. Body, glass and weatherstripping, no — the Sprint is the earlier Mk1 body. This catches people out constantly because the drivetrain crossover makes it feel like the whole car interchanges.
What's the difference between SF310 and SF413?
Engine. SF310 is the 1.0 litre three-cylinder, SF413 the 1.3 litre four-cylinder. Body and trim parts are generally shared; engine and drivetrain parts are not.
Do Pontiac Firefly parts fit a Geo Metro?
Generally yes for the same year and body style — the Firefly was the Canadian badge for the same car. Because Canadian-market catalogues occasionally list different numbers, confirm the specific part rather than assuming across the whole vehicle.
Is there an official cross-reference chart anywhere?
No, and that absence is well documented by the owner community. Khasis is building a free digital parts catalogue with every factory figure redrawn and part numbers cross-referenced across all five badges, published section by section as each is verified.
HOW THIS GUIDE IS SOURCED
Platform structure and chassis codes come from factory parts catalogues and published production history. The practical warnings — the Sprint mix-up, the 3-door quarter glass trap, searching under all five badge names — reflect three decades of owner experience across the Metro and Swift communities, written here from scratch rather than reproduced. Anything not yet confirmed against a factory source is labelled, not stated as fact.
