Trial fitted first to see fitment. Just had to do some minor trimming along top edge of rubber to remove excess height, and to allow the rubber to sit where it should up against firewall, otherwise very pleased with quality of the item. All holes line up where they should .My advise is to glue/tape, or whatever you decide to the firewall first, then mount the pedal box, otherwise rubber will just move around and you will have a hard time trying to put the pedal box in whilst trying to line up the rubber in place.
