Bob, thanks to your input and others here in the forum, I am negotiating with the shop. As of last Friday, I presented them with a list of other reputable suppliers that stock rebuilts and even offered to sign a waiver to mollify their concerns about product quality after the car leaves their shop. If things don't work out, then I might have to travel twice as far (I should enjoy the ride, right )but I learned of other shops that offer more competitive prices and are as competent.
