"273 Charger" Air cleaner decal install?

OK. I'm stumped. How do I install the "273 Charger" (or Commando) air cleaner decal and get everything to line up? I've tried taping it down first, marking certain points, but can't get the whole thing to line up correctly, or install without bubbles and creases. Anyone have a (hopefully) fool-proof method of doing this?
