Did you cut up the upper SVT grille for the billet? That is a hard grille to find, you can find the SVT lowers on eBay all day, but never an upper. It kills me to see people ruining hard to find parts. When I had my hood plastidipped, I used 3 cans and it still wasn't enough, cause it was very hard to remove.
If I was you, I would save my money and do it right the first time, trust me - I have been there with where you are headed & it's not a good place.
You can get a euro facelift grille off eBay for $50, I am sure that billet costed about $30. Here is the exact euro grille that was on my car, from the same seller:
I plastidipped that black and had it on my car until I got a Hofele
It is your car, do what makes you happy, but please look around and see what other people are doing.
You wanted advice on which parts to buy, please take it!
