These plastic side air vents are almost always distorted or cracked and caved in on the 330 & 365 GTC’s due to the metal spring retaining strap pushing on them from behind. We have made them in a much sturdier fiberglass to resist this distortion. They have the drain vent hole so you can now hook up the drain tube and stop filling up your trunk and inner rear 1/4 panel with water.
These are the same identical shape as the originals and fit perfectly. They are a big favorite with restorers when painting your car.
Tip – Fit these first, adjust as needed to mate perfectly to the inner pillar. Once fitted properly, then paint these your body color and then install them to have a nice finish inside the hole.
