160mm-180mm fans?

I have just bought a 96 GMC Heater Core for a Safarri (sp) van and well..... its huge. Lets just say, im going to be building a case around this baby. So my question is where can i find a 160mm or 180mm fan for this thing??

Because I can fit: 1 120mm , 2 80mm, 2 60mm fans on this thing.. that just an idea has to how big it is. I just need 1 though cause i think it will be enough and my HC will be part of my case so the air gets sucked out through it.
