You got it. I went ahead and ordered #3. It is from Classic but, not a Spectra. Some company out of Texas. The picture shows copper and brass and the tubes appear to have the correct bends compared to my factory replacement. Worse than the cost of buying more heater cores was the damage they've done to my heater box. I , naively believed because the vendor said they were correct and an exact fit, they were. I can repair the damage up to a point. I completely rebuilt the box, sanded down every screw, bracket, door, actuator rod, the blower motor too, all new seals and gaskets, you name it, painted all of the above and it's the heater core that has stopped me in my tracks?
