So... ive managed to get the old apron off but my god it wasn't easy. There weren't any other screws but it was wedged very tight between the playfield and the tabs keeping it in place. I had to lterally bend/pry it off. I also had to Dremel off the metal on the new apron as it wouldn't fit over the shooter lane(as someone else here also had to do).
So now I have 2 issues - one is same as above in that the opto cables that plug into board 8 are not as they appear in the instructions. My opto 2 upper cable has the missing connection on the left, not in the middle. So my question is - do we plug in as normal or do we absolutely have to ensure that the cable at the top of aux board 8 have the missing connectors in the middle?
Second issue is the software - I have installed .net core 3.1 but the Annunciator sofware still won't install and says the .net core is required...?
