whats the diameter of the stock alternator pulley?

[flyboy86]

Does anyone know? I'm considering replacing the stock one with a March Performance billet pulley, and I don't know what the outside diameter is, and also the bore size? Thanks in advance.

Do you have the tool to remove it? Just checking and giving you a bump !! I can measure mine tomorrow if no one gives you the information.

I don't personally own one, but the shop where I'll install it does have one.

I think its either 2.375" , or 2.75", but I don't know which!

Mine is 2.375" or close to it.
