I also mounted my fire extinguisher in the same location that you are by using 3/4 inch self-tapping stainless screws. For the badges I ground off the pins using a dremel tool and then mounted using 3M double sided tape that I found at Home Depot. For the badge location I looked at lots of pictures, found the left/right center on the front and rear and then eyeballed into place.
