what heater and rad hoses do i need?

well i already have the hoses, they are ordered from a 71 dart with a 318 and they line up perfectly with the rad, so im assuming that my rad will work fine shutting the hood and all...plus, with it being a street car i dont mind the extra size if its going to help it cool better...i really cant stand overheating and i dont want that issue, so hopefully this rad solves that...it should fit, and if it doesnt then i will have to do something about it, but for now it should work
