I know what I would do .. Take a picture like this
https://www.ebay.com/itm/Chrome-Kenw...-/141163539436 with the exact measurements of your grill to a graphics shop and have them cut it in chrome vinyl . I love the W900 with studio sleeper that your doing and it's got me thinking of doing one . Luckily for me I can cut that grill decal at home .
