Spitfire head size of damper pulley bolt on 78 Spit?

[tomshobby]

Hi, I am helping a friend with his 78 Spitfire. I need to know what size socket will be required for the damper pulley bolt? Since he lives some 20 miles away I thought it would be helpful if you guys could help with that info so I can take the correct socket with me.

Thanks much,
Tom

There were 2 different sizes, I bought both sockets. I seem to recall it's either 1 11/16th or 1 3/4. I would have to be home and look in my tool box to be sure.

Thanks, I didn't want to get there and not have a large enough socket. I will take some of my larger sockets to be sure.
