Somewhere in the free stuff there are texture templates for dork, posette, mike & vic that have color-coded areas to show you exactly where parts line up. I downloaded them a long time ago. If you overlay the appropriate one on a texture you're working on, as a non-editable layer (in Photoshop or whatever), you can line things up pretty easily. Just remember to delete that layer after you have things lined up, & before you do the final save on the file.
