'66 Wildcat Grill

Hello. I'm not sure if this is the best place to put this but here goes nothing. I am in the process of purchasing a '66 Wildcat hardtop sedan. If I am correct (be it rare), the grill on it belongs to a LeSabre. It doesn't have any LeSabre badges anywhere on the vehicle. The current owner has no knowledge of a grill replacement and the vehicle has been in his family since purchase. I'll try to include a photo of the car on this post. My question is; Was a '66 LeSabre Grill ever put on a '66 Wildcat at the factory? Thank you.
