Radiator Replacement Options

I have a 74 Dart Sport Slant 6 with automatic, my radiator split along the top outlet and there are no shops close to me that can fix it even if it is repairable. This is just an everyday driver so Im not looking to spend alot of money on a new radiator and was wondering if there is another solution out there from another vehicle that with some modification will work? Perhaps something from a Jeep 4.0 or something along those lines. Any input is appreciated.
