I am with upallnight. If you want to use your part you have to find a shop or mechanic with will take whatever and warranty accordingly. I have two indy shops I like here in Salt Lake County. One will use any part I bring them and one won't touch the job even if it is a BMW part I bring. His parts only or the highway.
