The Sparco seat base is a vehicle-specific mounting plate for the left side of 2003–2009 Mercedes‑Benz CLK models. It is intended to position and secure a replacement or aftermarket seat on the specified side, providing a clear match for CLK owners sourcing a side-specific base. The wording and fitment note in the source support direct selection for those model years.
