The Cold Water stub, which I did 1st was a Breeze. The Sleeve just Pulled Right Out. And it took Longer to figure out how to get the Sleeve Off the Inner Guide piece (you Turn the Inner Guide around 180 and the Pull it Off using the Old Compression Nut) than it did to Remove it from the Stub. The Hot Water side was a Different Story. It was a Long Vertical stub strategically placed behind the Garbage Disposal for Maximum Wrench Interference. In the end, I cheated by Cutting the End of the Stub off using an Imp.
