I cut a new hole with large rounded corners. The hole was cut little smaller than what the finished opening would be then the edges were bent down to help maintain strength. The opening for the transmission regulates the position of the new hole. The down turned edge was rounded similar to the original brake access hole. There will be additional strength added to the floor by installing a 3/4 inch angle iron, 12 inches long, bolted to the side of the transmission opening. The master cylinder access hole will be covered by a metal plate held in place with four screws
