While we're on the topic of heater cores I might as well ask..... does anyone know of a heater core that is equal to or a little less than these measurements - 11"L x 5 3/4"W x 2"D? The 5 3/4" measurement is really cutting it close

because the core would have to fit in my upper drive bays which I'm sure all of you know are also 5 3/4". I'm basically looking for one that can fit two 120mm fans, and has both barbs on one end. So let me know if you know of one that is close to these sizes. Thx
