slam panel would make life easier :)

However when I had a leon front light conversion on my Ibiza, I bought the slam panel for the leon, had the light fitments on the current slam panel cut off then the leon slam panel light fitments welded on. Guessin the mk3 ibiza slam panel won't bolt straight on.
 
mk3 slam panel will bolt on fine, but you will need everything...

bumper, slam panel, lights (and adapt the wiring), wings, wiper tray, new spray jets
