Looking for old Airac 1511 and related files

Hi, I would like update FSX (SP2) with the old AIRAC 1511 cycle (to be compatible with my Aerosoft's A320 Airac that is 1511). I also would like update ILS Vor etc. frequencies for that period of time.   Where I could find all of them?  I only find the newest Airac to download on the website.

Thanks!
