any 1 using a '65 musting heater core

ok so I purchaseda 65 mustang heater core on teh way now and I was wondering if any 1 is using one and if you are could provide me with the sizes or how many fans i would need and yes I've tried searching to find the size

Rockauto.com's picture shows a 8x6x2 double-pass core for the moostang. The problem is that those sites aren't very accurate.

Anyways, you can fit two 92mm's easily, or two 120mm's if you make a weird shroud that hangs over the bottom tank. Otherwise, it looks like a good core for a single high-cfm 120mm or anything bigger.

thanks
