They are interchangeable from a functional perspective, but not aesthetics. The deluxe ones do indeed have removable inserts, whereas the standard camera case versions don't. If you are looking for them, they some up for sale on eBay pretty regularly. But to find them not all pitted up can be a challenge. There is quite a price difference that is commensurate with quality.
I've got a couple sets in the shop, and will check later. I'm almost positive that there is no camera case below the aluminum "face". There certainly is none on the instrument cluster, the piece over the glove box, or the non A/C - non convenience control center piece.
