Now it has been some time since I did the swap on mine, but I do recall that the non ac core is much different. I believe the major difference is the houses or spouts that come off the core itself are shaped very differently. I believe the bottom hose on the ac version is much longer. Someone else can probably give you the specifics, but I do know they are different.
