What other hoods are able to fit a Chevy caprice?

The Chevy Caprice's hood is fairly unique to its body style, so direct swaps are rare. You won't find another hood that bolts right on without significant modification. Any other hood would require extensive custom fabrication, including:

* Modifying the hood itself: Cutting, welding, and shaping to match the Caprice's fenders and grille opening.

* Modifying the car: Adjusting the firewall, fenders, or other body panels to accommodate the new hood's shape and size.

Essentially, using a hood from another car on a Caprice is a major body modification project suitable only for experienced custom car builders. There aren't any readily available "alternative" hoods.
