That must be the same turquoise as my truck, which is the stock colour. Depending on the lighting, it looks either blue or green or somewheres inbetween. Looks like you will be putting a new bed in that box. I had to put in a raised bed because the '64 frames swoops up at the rear axle like a factory "C" notch and I had to clear that. Plus I put in a big-ass fuel tank behind the axle and wanted to keep it as high as possible. It''ll be springtime soon so you can crack open that door to let some light in for more pics and maybe some wrenching.
