Absolutely. Dante's should go to bat for you with the supplier. Out of warranty period or not, it was junk out of the box. They might not be able to get a refund, but they should fight to get a replacement. Garages do this all the time.
Crap. I just ordered the exact same part yesterday. OER brand from Classic Industries. I once had a quality problem on an expensive part I bought from them, and they made it right.
