Thermostat housings are very tough, but after 30-plus years, they have a tendency to rust out from wear and corrosion. OPGI now has the solution to a pitted or rusted-out factory thermostat housing with these extremely durable cast-aluminum housings. Manufactured to the exact factory dimensions, these thermostat housings fit and function just like the originals. They fit all 1963-76 Buick V8’s from 430-455 cubic inches.
