Hutch,
Thats what I was afraid of, why I only came home with the vents and controls. As far as the opening being different, bigger, smaller, different spot? I knew I'd have to cut for the vents and couldn't make up my mind on that one either. The outside box is well oxidized, I'll probably go ahead and get the one from inside just incase, I might kick myself later. It might be better just to go with the aftermarket air, I've got all winter to decide. Never actually added air to a vehicle, always pulled it. I'm getting older now, I need it.
jorgensensc,
I figured I would need that rod, I just ran out of time. I'll have to go back this afternoon. By the way, thats one nice truck you've got there!
Thanks guys.
