So, you stagger the holes side to side every three inches in the aluminum. Then drill corresponding holes in the liner put the aluminum on the inside with the screws sticking down and put on the lock nuts with big washers. so you can remove it easily if you have to get back in there.
One possibility would be to take a 2 inch wide piece of aluminum strip. Cut it to length, and then pop-rivet every few inches on both sides of the cut.
