I took a quick look at the WatchCo eBay site and they do have a steel caseback and (dome) dial for the Ref. 167.005. Prices were not ridiculous, but postage from Australia to the US usually is. A spare pie-pan dial in good original condition could go upwards of $400, if you could find one. More if it has rose gold markers.
That still leaves you short a lot of parts. All of which are probably obtainable, but at what price and cost? In other words, it may wind up being far more expensive to put together all the pieces, than to buy a nice ready-to-wear vintage Constellation.
Ordinarily, I would say to scour eBay for a non-running example and have a watchmaker exchange the movement. However, that may easier said than done, since these cal. 551 movements are so good that when a non-runner is found, the case and/or dial are usually trashed as well.
But you never know....

P.S. - Here is the dome dial for cal. 551:

The one you posted above is a service dial for a different caliber and probably wouldn't fit either the movement or the case.
