RE: Grill color
The paint is Light Argent Silver Paint, this was used in grilles , trim panels, and 1970 Rallye wheel center caps, call these people 1-800-932-7663(Year One). Ask if part #QP8575 is still available. This product is can only, not spray. So a body shop or somebody with a paint gun would have to do it. Even though this is the same color it says it Flat Light-Silver paint-it is used on the Rallye Wheels- Part #FD1469(this is a spray can), if your not looking for orginality, as far as paint.
P.S. The QP8575 says its the correct texture paint.
