Resize AI Postcard for Print

I have an existing postcard design in an Adobe Illustrator (.ai) file that simply needs to be resized for print. The finished art must measure 4 × 6 inches plus a 0.125-inch bleed on all sides and be set to 300 PPI so that the printer receives a clean, press-ready file...
