If you measured from the back of the rear cross sill, that will be what he needs.
Chadd, Attached is a pic of the sketch I made when I was restoring my bedsides. I needed to replace some of the metal around the bolt holes. Use lumbersawyers measurement as a datum point. It'll be the one that's 4-7/8 from the front of the rear stake pocket. Note that all of my horizontal measurements are referenced from the front of the stake pocket, so you'll need to adjust them (or use that as a reference point after you install the rear stake pocket.
Hope that helps.
