Genuine GM brass radiator petcock designed for classic Chevrolet models including Camaro, Corvette, Nova, Impala, and Chevelle

BRASS PETCOCK WITH FLUTED END

Technically correct brass petcock for original style radiators.  Often, replacement radiators come with a plastic drain plug which is incorrect.  These were used on thousands of GM vehicles throughout the 60s and 70s. 

Correct replacement for GM P/N 9427524.
