1968-1982 C3 Corvette Headlight Vacuum Line Check Valve And Filter
 If the headlights are acting up on your Corvette then you may need to replace your vacuum check valve and filter. The check valve is used to ensure that your headlights only get vacuum so they will stay open. This package replaces original GM#3926296 &  5638432.  These are GM reproductions authorized and are factory correct and proudly made in the USA.
