I had my Dana 44 set up there. They were good to me and charged about 150 for the install. Turnaround was two to three days if I remember correctly.

neither one of your story sounds like anybody getting screwed.the first one sounds like an installer mistake. It's unfortunate but it happens at all shops and it sounds like they are going to make it right. The second story could have been a multitude of reasons. but not likely that it was an installer mistake.
