Product review (4 stars): Takes some effort
The parts fit as expected but take some real effort because you are working in such a difficult location and working mostly in the blind. I removed the original back pipe and blank on the left side. I then took pictures with a digital camera through those holes which helped me understand the connections inside. I also reviewed videos on the Internet that applied to this kit and it helped. I taped all connections. The install has been working for about ten months with no problems. The inputs from others on using gloves, tape to avoid cuts around openings and pre-assemble outside the unit to make it fits I also used.
