No takers on question?
Ok, Bullitt is easiest.
Identical bumper to GT but plain grille.
No fog lights nor pony in grille.
Thin polished metal grille surround from one sibe through bottom part to other side.
None at the top.
To confirm it’s a Bullitt it must be black or dark highland green, only 2 colours abailable.
Next GT/CS or California Special.
Same grille as GT complete with fog lights and Pony.
Difference is the bumper.
Top part of bumper identical to GT with no indent for front plate.
Difference is all at bottom of bumper where there is a faux or imitation splitter. Only it’s not a real splitter. It’s more like a bulge or chin at the bottom of the bumper.
It hangs a fraction lower than the GT bumper and the middle part of this chin is painted black the width of the lower opening.
Each side of the black is body colour.
Real keen observers at an angle allowing to do so would also observe a slightly wider body at door hight and maybe two black spots.
These would be the faux side scoops that were part of the GT/CS package.
Bumper and scoop visible here.
Last is the GT500.
This one stands out the most as being something different.
First a bulge on hood from heat extractors.
Many with over the top Shelby stripes.
Grille has no fog lights or pony but a Cobra snake on driver side, so to the right part of grille when meeting the car.
Grille is also angled wider on the way down on each side so headlight lenses also have this angular or diamond shape on each side of grille.
Different from V6 or any GT variant ie Bullitt or GT/CS.
Bumper also different.
Lower opening has reverse angle to grille where it gets wider from bottom up and has smaller fog lights in the bumper, one each side of lower grille opening.
Both upper and lower opening combine to create like a happy face smile.
Finally a true black splitter at bottom of bumper.
Sorry Hugh, couldn't find one in blue and white with this clear front view.
