Simmer's Sky AFCAD 2

Good day mates.I've purchased some Overland/ Simmer's Sky japanese airports.They look pretty good and detailed, however, it's seems they miss an AFCAD 2 File, thus the parkings and rolling AI (UT)Trafic are slightky displaced.Can anyone advise if and where such AFCADs may be sourced?Many thanks in advance.Fortunato
