Not wishing to cause issues but some were raised letters not flat decals like the ebay ones. It depends how much it bothers you if it turns out yours were. They are however very hard to find in sets and you may have to buy another bonnet or tailgate with them on!
Raised letters were from around KA chassis number onwards, so the very last hard dash models and all soft dashes. Bonnet/Tailgate lettering is the same.
