To achieve a correct fit, some adjustment may be needed for Reproduction Door Panels. When installing either the front or rear panels, tilt the bottom out at a 45-degree angle and gently move it side to side to position it correctly. You'll feel it settle into place with a slight pop and lay down smoothly. Afterwards, assess if any minor adjustments are necessary for the metal top rail. Also note that these panels feature aluminum trim moldings with cut ends, differing from the factory stainless steel ones. For a visual guide, please refer to the YouTube video demonstrating the installation and adjustment process for Reproduction Rear Door Panels.
