My Auto-Electric guy didn't have one of the +/- 3" pulleys in his bone pile so I bought a 3.9" C5AF-H version from eBay. $41 to my door.
If it's here by the weekend I will try it out. Still need to get a bigger belt too.
Regarding the thread projection thing, I have full engagement of the thin nut supplied with the 3G using the stock 2 3/4" pulley. Hoping for the same with the new pulley.
