Extra attachment points for the nose panel to the radiator support on the sides. The nose panels are different too from memory to allow for this. I can't actually confirm that it is HJ that is different, I have just assumed it is HJ and the tabs and holes were deleted at some stage. I remember seeing them on nose panels and radiator supports when I used to make them up out of smashed ones back in the 80's. I'm pretty certain the first time I saw them was on a smashed nose off a HJ Caprice, and it being in original Chamois paint, still with a mangled HJ Caprice grille and badge, so have always assumed it was HJ. I'll check my Prem out one day and see if it has them. They are really hard to see with the guards on.
