It may have possible uses for a Chev CMP or similar vehicle.
It appears to be expensive, but if you take a CMP radiator to your local radiator business for a recore, don't expect any change from $800 , possibly more .
The movie company I sold my 1941 Ford to, back in 1992, had the radiator recored , cost them $900 .
