Both of the Curt hitch receivers have the same bolt hole measurements. It's 9 inches from the first hole (Closest to the front of the truck) to the second hole and 5-1/2 inches from the second to the third. There's 39 inches across from hole to hole and from the tip of the receiver opening to the furthest point towards the front of the truck is 28 inches.

The one measurement that is different is from the bottom of the receiver tube to the top of the brackets where it mounts to the truck. The # C15312 is 5-1/2 inches and the # C15313 is 8-1/2 inches.

I've attached some diagrams to help.

They're both confirmed to fit a 2007 Chevrolet Silverado 2500 8 foot bed and 3500. The difference is the # C15312 is for models with the factory cutout bumper and # C15313 is for models with a 10 inch deep drop bumper.

If there's other measurements you're looking for just let me know.
