1965-1966 Rear Quarter Extensions


  • Model: FG-Qtr-65-66
  • Quantity:


These rear quarter extensions feature easy bolt-on application and compliment our rear trunk spoiler or deck lid perfectly. They are the only ones on the market that are already higher where the top of the quarter meets the extension. This is so you will not have to build them up to match the deck lid.

Our quarter extensions have a return lip for easy adjustability when installing and studs with already mounted in for you. Please watch the YouTube installation video for a full explanation of these extensions.

Note: Always make sure your deck lid with a weatherstrip is bolted on the car before fitting the extensions.

The Mustangs To Fear Fiberglass Difference:

There IS a difference when purchasing a Mustangs to Fear fiberglass body kit or any of our fiberglass products. We have included some side-by-side comparison photos to prove that when you buy a Mustangs To Fear fiberglass product, you're truly getting what you pay for which is superior quality and fit compared to our competitors.

NOTE: The rear bumper, quarter extensions and rear spoiler (for coupe or convertible) or deck lid (for fastback) all line up to work together beautifully. Since they were designed to work together please do not try to use them separately.
