Belt Size?

[ANIL8-U]

I just installed a crank pulley on my 98 GTS and I need a part number or belt size. The pully is 25% smaller!

PS, I have A/c

No body knows.
Your in a hackers world.
Try rapping a string around the pulleys and go to the auto supply store with knowledgable staff.
7 rib belts are rare to begin with. Let us known how you did.
