Hello, my vehicle is [make, model and year]. I [have already bought a part, with number and source: … / have not bought it yet and am considering: …]. Please confirm whether you accept customer-supplied parts and what information or checks are needed to assess compatibility. If unsuitable, please stop first and explain charges for checks or disassembly and who handles return enquiries. Separately explain the contact and scope of support for problems with the part itself and with installation, and quote labour charges. Installation is not yet authorised.
