Small auto parts are easier to identify when the listing shows the maker or brand, part number, dimensions, connector or mounting points, and the vehicle compatibility you can verify. Do not call a part universal because its shape resembles another one. Keep packaging labels and supplier references with the item record.
Photograph both sides, connectors, holes, threads and any marking in focus. Include a ruler only for dimensions you measured, and do not expose private supplier invoices or vehicle-owner data. For a used part, state condition and what was tested; for an untested part, say so before a buyer relies on it.
Ask for the vehicle make, model, year or engine detail needed to check fit, then compare it with a reliable catalogue or supplier record. The buyer should verify suitability before installation. Confirm payment, delivery, installation exclusions and any return terms directly; the seller, not the listing, arranges fulfilment.
