Duster Survivor Radiator Dilemma

well the key is finding a GOOD rad shop. they will soak it in their nasty stuff. pressure check to find where it is leaking. the tank, the core? both? sometimes the core can be rodded out. if the tanks are good and needs recore, last on I had done this spring cost me $265, it was a 2 core out of a Lancer . other slant rad will not fit without cutting up the support.
if the car is worthy of keeping original and striving to be recognized as "survivor", work to keep the orig rad in there.
