Semi Truck Truck Bed Floor Supports

There was not a warranty car, instruction, nothing in the box. I can buy a 2 dollar toy that has a book of documentation. No directions. There are four sizes of rails. The biggest one goes to the back of the cab. It has an indentation that goes on the driver's side. The one with the two lift ups different than the the other two goes to the very rear. The tallest of the last two is the 2nd one from the cab. The last one is number #3 from Cab. They should tell you that the kit comes with most the bolts. You can destroy the factory bolts and clips that hold the bolts to the frame during removal.
