it was the right part but made wrong
it did not stop the sink faucet from leaking - evidently delta has bad quality control on their repair parts.  we install the one we ordered and it leaked like a sieve.  went to Lowes and bought one...still the same...went back to lowes and bought another and it worked...so be cautious with delta repair parts...may be easier to get locally so you can buy many and take back all the ones that don't work.  this vendor did a great job on the order and delivered fast.  no problem with the vendor...just the parts from delta.
