Quoted from LongJohns:As other mention, bad display. Had to replace one myself not that long ago and wrestled with the option of buying a new glass or switching to the LED display. Ended up going with the glass as I prefer the OEM look.
Be aware though that there are differences in the displays when it comes to the nipple position on the back. The Pinball Life one would not work with my board according to the nipple position graphic they have. I ended up buying from Pinball Resource as it had the nipple location on the other side.

+1 the PBL 7 digit numeric glass did not work in my early F-14 display. The Pinball Resource glass was a perfect fit.
