Thanks, I bet you're right. 1/4-20 ( I can hope can't I) is just a little too big so I'm getting the 6mm bolts tomorrow. Thank you for your quick reply.If I had to throw out a fairly educated guess I would say 6mm, I could check tomorrow night if no one else chimes in.
Good info. I need to replace my cable sometime this week, and probably would have tried half the sockets in drawer before I landed on a 7mm.I know it takes a 7 mm socket
to remove them
