Getting the Delta out was a serious pita because I couldn't feel the nut shown in the pic. A 17mm deep socket finally caught it - it was so loose from all my wrangling it came off easy. Basin wrench just wouldn't play in there

The Anabelle went in smooth - the same 'finger style' washer and a larger nut to clamp it down. I didn't realize Moen actually supplied a plastic wrench! I used an old oxyger sensor deep socket (the nut is actually a 21mm).
No leaks - the Wells A124 adapters work perfectly.
Huge improvement!
Dave,
Thats a great looking faucet.
Drilled the hole for the soap dispenser today. Went with 1 1/8th" to give me more 'adjustability room'. Had to lower my undersink filter, but no drama...
What kind of bit did you use and how much, if any, chipping did you get in the Corian?
Milwaukee bi-metal hole saw (Home Depot - 10 bucks), drill on slow speed, moving the saw in and out to keep it clear. About 7-8 minutes to drill the 3/8-1/2 thick Corian. I then sanded the hole and edges as recommended with 100 grit to eliminate micro cracks.
