Thermostat Housing #3958002

I have #3958002 housing. Is this correct for '66-'67 Big Block?
Thanks, Michael

Absolutely not. However, while it's not configurationally correct, it is functionally correct. The GM #3958002 was released in 1969 and, if I am remembering correctly, is very similar to and functionally interchangeable with the GM #3877660 which was used on most 1966 and 1967 Corvette big blocks. In any event, since it had not been released at the time, it would have been absolutely impossible for it to have ever been originally installed on a 1966 or 1967 application.
