'78 radiator-will it fit?

[lukecp]

Will a 4-core radiator from a '78 Chevy C-10 with a 454/TH400/AC bolt into my truck? The two core i have in my truck now just ain't cutting it, and i can proably get the radiator out of the '78 for next to nothing. It is also a sealed system, with a coolant recovery tank. I measured it's width, and length, and it is almost exactly the same as the one in my truck. I am worried about the mounting hardware though. My truck had a 4-core, and i am currently using the brakets on my 2-core. Also, are the tranny cooler lines at the same height? They looked a bit lower on the '78. Thanks for any help.
