Jim, that’s mighty kind of you. I will get better information.My 2003 is in pieces so I can measure what you are looking for. Unfortunately, your description is not clear enough for me to know from where to where you are asking. A picture or a sketch would really help.
But I have a more pressing question. I can’t find any documentation for roof rib spacing, and width of ribs. I’d like to install an 11” ceiling fan (cutout size is 11x11) without taking out the headliner. Any help there would be greatly appreciated.
