I don't think I'd be too happy with obviously used parts like the wheels. I would have called them back and asked for another set unless they were going to give me a credit for used parts. Heater cores I would never trust, I get mine recored with the same style core that they came with, mind you those are getting hard to find too. I just had one redone for the Challenger, rad shop bought up a bunch of close out cores, simply swapped my heater tubes into a properly sized core.
