Those wheels are a replica of a Mustang wheel, I think the closest to your picture is probably this one although it's a dark matte charcoal...
Mustang AMR Charcoal Wheel; 18x8 (10-14 Mustang, Excluding 13-14 GT500) - Free Shipping
There are a bunch of wheels from different manufacturers though that are similar.
The problem you're going to have is getting the front and rear sorted out together. You won't have any issues finding offsets that fit the front, the +30mm offset available on the AMR wheels would work great in the front and in general the modern wheels are pretty easy to find in +30 and +35mm offsets.
The problem is it won't work in the back with a stock A-body rear end. The 18x9 is also a +30, so that makes the backspace ~6.1". And in 9 and 9.5" wide wheels the most common offsets in wheels like that are still like +30 to +40. But with a BBP A body 8 3/4 and the stock spring locations the offset you'd need is more like a +12.
There are also these, they have an 18x8.5 +35 for the front and an 18x9 +15 for the back that would likely work. The hub bore on the rear is going to be tight, but it should work in the rear only. Again, they're a graphite color. Konig offers the wheels in a darker color, but I couldn't find them in the right size/offset
