Well, while I waited for the heater core to get here I got tied up in other stuff but yesterday decided to service the tranny and change the oil in the motor, while under the car I noticed coolant on the ground, come to find out the lower radiator hose outlet has a pin hole where it was brazed on, so I guess today's project is pulling the "new" radiator and fix the leak, was hoping to get the heater box all back together and back in the car, oh well....
