Ken Mitchels a320 a330 Panel question

Hello AllSimflight seems to have gone comatose so i thought i would try this here..... I am probably being IMMENSELY dim but i will ask the question nonetheless.I have a lot of IFDG and Project Airbus A320s and i use the well known panel by Ken Mitchell.Recently i have been trying the opensky A330 and Ken Mitchell also has a panel for that aircraft to.Both panels look identical and my question is this should i use the panel by Ken for the 330 or are 320 and 330 the same.I KNOW... DIM or what cheers Andy
