Radiator is leaking...replacement options?

Hi all,

recently found out my 74 dart (225 slant 6) has a bit of a radiator leak. not sure how hot its getting, all my gauges minus the ammeter dont work, but theres a pool of coolant at the bottom of the radiator. In addition, someone put an incorrect hose (too long, rubs on underside of hood) on the top of the radiator, and the lower hose is bulging a bit. Does anyone have a good source for replacement parts, as well as any tips/tricks to changing out the radiator?


Thanks!
