Thanks for input and specifics. Looks do-able when weather cools. I estimate I might need about 2 hours from start to finish. As a stop-gap, and to buy me some time, I am going to try to slip a larger tubing around the short stub that is still attached to the unit. The stub is not that accessible, but I may be able to attach the larger tubing using some silicone adhesive.
I also realized I could attach some tubing to the bottom of the drain hole on the bottom of the inside drain pan, and run the tubing to a container on the bottom of the refrigerator inside. Not great, but a temporary fix.
Thanks again.
