Cross-referenced parts are cataloged as fitting the same application but are not guaranteed to be identical to the original manufacturer part. Verify fitment against your OE number or VIN before ordering.
Reference/cross-reference numbers vary by engine, transmission, chassis and production date — not by number alone. Before ordering, compare your original OE number against R21 number by MGA listed above, and check the dimensions or specifications against your original part.
If you’re unsure, contact CarBus24 with your VIN or the number printed on your original part and we’ll confirm the correct match before you order.
| OE (SACHS, Ford, Mazda) | Aftermarket (FAST, Valeo, LUK, Exedy) |

| Typically higher price | Typically lower price |
| Direct OE part number | Equivalent fit, different part number |
Compare your original OE number against the OE Reference Numbers listed above, and check the dimensions or specifications against your original part.
