The price was good. Item arrived promptly and seemed to be correct dimensions, but when installed it I discovered that it was a little too thick to allow the damper to work correctly. So I had to take it apart again and do some custom work on the back of the combustion package to make it go back further so damper would work. There were no instructions included to explain this process.  Hopefully, it will be good for another 10-15 years like the original was.
