Need help with my console

[1972Blaze]

Attached is a picture of part of my console. I have disassembled it to begin restoring it, but I'm not sure what to make of it. The seatbelt section looks like it may have been cut out of another console and screwed to the top console section. Any thoughts as to what the original configuration of this console was? Were the cup holders originally a screw in insert? Were cup holders ever original to the 72 model year? Was the seatbelt holder molded into the console body?

Thanks for help with any of these questions.
