Gday John, You 'ideally' will need to source the Leading Edge decal set as it comes with some great detailed information on accurate size and positioning of all the markings, this will make the job easier. I used these decals to work off for my SM bug.... I would be surprised if you could not source these from somewhere. Let me know if you have no luck and I will dig through my documentation and see what I can assist you with... check my gallery for a pic of my 20th anniversary CAF bug.

Cheers- Marty
