Swapping engines

Thanks, you guys. I already tried the socket/screwdriver method yesterday, but I can't seem to get the nut tight enough so that the stud doesn't turn. It needs to be fairly tight before it can be torqued. I'm going to try again, turning the socket with vice grips, protecting it with a shop rag. The problem is that only a small screwdriver will fit through the socket, seemingly too small to hold the stud. Nevertheless, after working on it all night in my dreams, I'm going to have another go at it. The hopefully thinner-walled box ends won't be here until later today anyway.
