Do not assume interchangeability for transmission-related parts. Check the fitted gearbox and control system against the individual product application.
Check the production series and body style, then record the engine and transmission details. Modena and Spider; competition and special versions require separate checks. Compare the fitted component with the product's stated application before ordering.
Compare the complete number, including any suffix, and check the listing's applications, dimensions and mounting details. If the car has been modified, identify the fitted component as well as the original vehicle specification.
Read the individual condition label and description, and review the photographs for storage marks, wear or missing fittings. Check whether the price covers one item, a pair or a set; condition and quantity are product-specific.
