The repos are fiberglass, not injection mold plastic like the originals. However they are based on a mold made from an original shroud.
Outside finish is decent, may need some imperfections filled, sanding and a repaint.
Inside finish has the fiberglass mat texture.
The mounting slots and holes need to be cut.
Kirban performance had them made and they are resold through various parts vendors. They may or may not be in stock.
If TPP is out, he (Dennis Kirban) was doing limited runs and selling them for around $125 from his shop.
I've modified a 300 shroud to fit.... turned it upside down and trimmed a few inches off it's depth.
