The Sparco right‑front seat base for 1970–1974 Pontiac Firebird is the matching mounting bracket to install a compatible seat on the passenger side. It provides the correct orientation and factory‑location bolt points for that model and year range, serving as the structural interface between the seat and the vehicle floor for a secure, vehicle‑specific installation.
