M / Delco Moraine 5455493 – 906‑S is part of the 906‑series, a later‑generation Delco brake‑service kit family used on early‑1960s GM full‑size cars, especially Chevrolet and Pontiac. These kits are less common than the 904‑ and 905‑series and tend to command higher NOS value because they fit high‑demand restoration platforms.
