Under the Straw Hat
This part may not be visible once installed, but its purpose is critical. GM designed this insulator to guard the primary forward body mounts from splash zone debris and temperature fluctuation. A missing or crumbling shield here can speed up mount bushing deterioration—this reproduction keeps your Corvette riding right.
Because Details Matter
Rebuilding your front body mounts without this piece leaves your restoration incomplete. From driving comfort to judged accuracy, these OE-style shields lock in functional authenticity and extend the life of your investment.
