steeda underdrive pulleys size belt?

[eblack99]

I have a 99 GT Mustang, I purchased 3 piece Steeda underdrive pulley set, I want to know if I'm going to need a smaller belt or will the factory belt work? the balancer is smaller than the factory one thats why,

thanks,

Yeah, stock works. The alt/crank are smaller, while the water pump is later which evens it out!
