Paging Mr. Drano ...I'll let him chime in with all the different "hardware configuratuions" he's been trying in his game to get the spacing figured out.
For what it's worth, the first photo of my Star Gazer shows no spaces between the credit/ball in play numbers. They are positions 3-4-5-6 of a six digit display (if I recall correctly). It's running a Alltek MPU with @acebathound's Retrofit conversion kits for the displays. The backglass is a Greatwich repro.
The second photo below is uploaded to show the spacing of the window on the swing-out display board, if that makes a difference or not. Pay no attention to the garbled displays--the picture was taken before I wiped the memory of the Alltek. FWIW, my backbox harness tag had "BIG GAME" stamped on it, and the game itself was likely one of the first to roll off the production line.
