Thanks for the info. I want the socket for future ease of removal. This is the third transmission job and won't be the last I'm afraid with 5 cars. I need to know which of the 3 sockets will fit the driveshaft flange. I will measure the nut and call them today. I have tried to beat one of those nut out of that recess before and had no luck. I finally took it to a local shop to have the nut removed for $20.
