4.54 out of 5 stars 83 Customer Reviews

When replacing your muscle car's quarter panel, often you'll need a trunk floor extension, as well. Auto Metal Direct offers direct replacements for the original extensions on a wide variety of makes and models, particularly cars from the '60s and '70s. They're manufactured from high-quality steel and then EDP coated for excellent rust resistance.
