i cut holes in my fender well for changing plugs and getting to the idle jets and carbs. they are about 4-5" wide and 7-8" tall. i used a saw zal or however you pronounce that. its the freehand jigsaw one. drill a hole about how low you want the hole to start and then look inside the engine compartment and see if its low enough. just line up the angle of the spark plugs and draw an imaginary line to the wheel well. or dimple it with a punch to get a good outline of where you want to cut then do so. then get a scrap peice of metal to make the flap. some people make doors, i just used four sheet metal screws to hold it on. very nice to have i must say. hope that helps. if you really need photos i can take some but my engine is out right now so you cant gauge it in reationship to the carbs and plugs.
