Face lift Cupra grille is a one piece moulding that clips in behind the metalwork and fills all three upper cutouts with the appropriate size honeycombe section. Approx £120 from a stealer.
If you get a high velocity pheasant through one section you have to buy the whole unit
The central section with the Seat S on is slightly different dimensions to the LCR one as the LCR has the small horizontal vent as well. ASFAIK you cannot just do a straight swap though some skilled types have managed to "bodge" it.
