Did Oz delivered Capris come from the factory with the Falcon GT Superoo decals on the front guards 
 
If so does anybody the measurements for the placements
 

The V6 capris came out with the Super Roo decals.  Unless you opted for Delete Option where stripes bonnet patch and super roos were left off and the GT badge was re-located to the rear quarter.  To see where they go there is no official measured placement.  Have a look at the factory brochures that should show you where they go

See the attached two pages from the official Capri Parts Manual.
 

Or this official Ford two-page brochure!

Theres a sweet spot where it looks good about equidistant from the bumper, the wheel arch and the horizontal side crease.
