My 2 cents is…. They don’t care. They sent you a replacement box and great for you it’s better. They have moved on.I don't think so since... 1) I couldn't read the numbers on either box, 2) they had the first box picked up by UPS and then they shipped another box of the "same" load to me the next week, 3) all this took several weeks to complete from the original purchase, 4) since the load's components were different and closer to specs I must assume that they loaded those for me since (I think) they knew I would probably open, measure the components, and pattern them!
Sorry for being blunt but since they haven't been able to find the time to at least have someone contact me and answered some of my questions, I'm left to draw my own conclusions on these questions.
Anyway, now you can be the judge!
