I could be wrong, however I believe the superoo decals were dealer fitted like wiggy333 said above
These were added a as a marketing trick to align the small fords with the performance image of the Falcon GT's.
Thus the actual positioning of the front superoo decals differs slightly, dependant whom fitted them at the dealers.
This also could also be the same for the bonnet pins.
For example
Early cars got the pin type pins from XW GT as that what the dealers had access to from their spare parts departments from the XW GT parts bin.
Later cars got the screw down pins from XY GT, however these must have been a "genuine accessory" as the brackets are Capri specific.
I havent double checked my Capri parts catalogue book but I can't recall the superoo decal and bonnet pins listed as Capri parts in the parts catalogue book.
Just my 2 cents worth.
