Here is the '55 two-door post project car at Firehouse Fabrication. It's been the host of many updates and it's not stopping there, sounds like a perfect candidate for the power hidden gas door.

When it comes to cars, our "point of focus" can either make it or break it for us. On one hand, there might be this wicked-awesome Tri-Five in front of us that's just firin' on all cylinders. Yet, on the other hand, some minuscule piece sticks out like a witch doctor at a baptizing. It's those little things that really dig in deep, and they often helps us decide whether we like a car or not.

Leave it to the aftermarket industry to save the day. Rocky at Rocky Hinge has developed something new for the '55 to help smooth the edges and redefine the bodylines. He developed a hidden gas door to replace that ugly flap-style gas door, located dead square in the middle of the left quarter-panel. Rocky made it possible to relocate the gas filler behind the taillight, like on the '56 and '57s, but made the taillight open electronically with the flip of a switch from inside the car. Talk about a cool way to shift your point of focus off that gaudy gas door.

To see just how meticulous a system the Rocky's kit is, we took a short trip to American Muscle Cars where fabricator Brett Maxwell had our project '55 Bel Air anxiously awaiting the subtle yet significant change.

    Trim the lip in the taillight opening so that "part A" will replace it once it gets welded in. When fitting and trimming, make sure that from the outside, bottom of the taillight opening to the back of the motor plate(towards the front of the car) measures close to 8 1/8 inches.

    With the filler neck plate attached to the motor plate we can see that it fit pretty well inside the quarter-panel. With both sheet metal pieces fitting well and measuring correctly "part A" gets tack welded in.
