Here is a pic of my truck in my door. Sorry for the bad picture but I took this with my iSight camera on my laptop because I could not find my camera, therefor, everything is backwards. Anyways, this door is less then 9ft. About 8'10". As you can see there is about 3" on each side of the mirrors. It is tight squeez but it works. You will have no problem with a 9ft door. It fits with the mirrors extended as well, just very very very tight haha. Hope this helps.
