Some stores will allow u to upgrade , if u pay the difference!!! I've had oreilly in the past do this, when I had replaced a wiper motor two times within 8 mths!!!!!

 

I have never had any luck with parts that are not AC or Delphi in any GM vehicle I have ever owned. I learned a long time ago it is always worth the price to use those parts in my Chevy's no matter how much more they cost. GM vehicles just do not like aftermarket parts of any kind.

 

Check Rockauto.com we got a fuel pump for my Buick Regal for half what the local parts stores wanted. It was a Delco pump to boot!
