Eddie I cut them up into 4 pcs. for easier installation and future repairs. Front pc can come out without removing seat.. I make out of old 1/4 inch plastic signs(can get free from sign shops as they throw them out) I do not cut out that inspection hole at bottom it makes a weak area.
pc 1 in front of seat holes
pc 2 and 3.. sides from seat holes and 4 the square left over.
The metal pc. that gas pedal in on often rusts out so I have replacement Fiberglass panel for there.
