Honda Civic throttle body.. (xx)mm?

[jeffrey]

Does anyone know off-hand what size bore (mm) a 1998 Honda Civic EX coupe's OEM throttle body is??
I see replacements online ranging from 62mm to 70mm, but those are larger than stock. Thanks to anyone who can help.

Somehow 56 or 58mm sticks out in my mind. Don't quote me on that.
