Hello Grayson. Next step, before analyzing, is to clean the whole area. Wire wheel or sand blast or other. You may see more problems. So get all the dirt, grease, scale, rust cleaned up. (I know that you know that metal has to be clean to weld anyway). Then you can see if there are patch panels available and/or fab up some patches. The general rule is not to cut out any more than is necessary, except for welding considerations and strength. Does look pretty solid except for kick panels/inner cowls
