I'm not real concerned about the car. I do have to bring it back. I have a feeling they are attached to a chanel. But how or why would a car company put 2 floors in a car??? The real ? is the carpet is under the rails so that had to go in before the rails and before the floor?? I'm begining to remember why I'm not fond of working on ford products. Tomorrow I think I'll take an air chisel to the bottom of the car and see whats there. Are ford mechanics all HODENIES?
