I've replaced this part 2 times in two years.  It cost's $58 bucks.  It's a piece junk.  Customer service has offered me one for half off at $28, plus tax and shipping.  I found the same oem part on line for $35.  How can delta add 40% and justify it? I will be replacing this part but will not be buying anything else from delta when I remodel.  Their customer service is good at saying I'm sorry about this and I'm sorry about that, but not sorry for not doing anything to improve.
