1999 wheel hub question

I was going to change my wheel hub today and found out I don't have the right socket for the axle hub nut. According to advance auto I need a 1 5/16" socket for that and of coarse I went to about 4 stores (Advance Auto, Northern tools, Ace Hardware, Lowes) and nobody has that size in a deep socket variety, which is what I would need. So I found one on-line that I was going to order but I just want to make sure that that is the right size to save me time for returning it if it is not. Thanks for your help.

It is a 34 mm socket and the Advance auto or Autozone around here has them. Look at the Leslie display(specialty tools area). That is where I found mine. Do not use a impact drive to install the hub it will destroy the hub.

Thats what I thout it was origanally and the guy at advance auto told me no the computer was saying I need a 1 5/16 " not the 34mm. I will go to a different advace auto by my work tomorrow and see if they have the right one. Thanks for the help.

Well I tries the 34mm and it is too small, looks like I need a 35mm. I saw sears has these on-line and it says this size is made for most GM cars. Anyone else know what it could be. Please help.
