First off, get yourself measured so that you know what size cockpit you need. Put on your firesuit, helmet boots, gloves, sit down against a wall, bend your knees until your outstretched hands just touch your knees with your heels on the floor. Now, roll your shoulders flat to the wall, and have somebody measure: floor to 2" above helmet, width outside to outside of your shoulders, from wall to your palm, from midpoint of your upper arm to the floor. These numbers will tell you what you can and will not fit in, bigger you can pad the seat to fit, small you you will not fit!
