Stock crank pulley size?

Hi all,

This might sound a bit odd...but what is the width of the stock crank pulley? I've got a project that I'm working on using an m90 I grabbed from the JY. I have a couple crank pulley/SC pulley options so I want to roughly figure out where I should start. I realize it's not going to be an apples to apples comparison, but I'm just trying to get a ballpark pulley size that I should start with. Thanks.
