Photos of my 1969 2B Norwood RS Z/28 during teardown. I'm confident based on tell-tale indicators that neither the manifold nor the thermostat housing had been off the car to that point. In fact the housing stud had fused to the aluminum manifold and destroyed the degraded threads on removal. The 660 housing has the part number embossed on the neck rather than the flange in this case.
