On my bro in laws rig we ended up with a 112" wheelbase after moving the rear axle right up to the cab. We used some rears up front packs to move the front foward about 3" and linked the rear. While building the rear he was worried the tires would contact the cab becouse it was close. I'm pretty shure the stock 3rd gen extended cab wheelbase is 12+ inches.

That looks just like "Project Blu"
Close anyways.
