Belt size? Pulley size? Where to buy?

[grey03mach1]

I just aquired an 03 Cobra with 50k miles last friday. It has a smaller pulley on the SC'er but do not know the size. My belt also has a small cut on the outside. It will sometimes slip under WOT and squeal a little. It also has a little to much slack. I am going to buy another belt and may also consider purchasing a tensioner to ensure it stays tight. Problem is I do not know the size of the pulley. It is a motoblue brand and I think it is one of the smaller ones because it is about as smaller as it can get. Where is a good place to purchase another belt and a tensioner?
Thanks for the help
Matt

take the old belt off and go to NAPA tell them you need it 1inch to 1/2 smaller should be good after that

Do you think that a belt tensioner is a good idea or is it not necessary?

Go with an auxiliary idler. It will help alot with belt slip.

My bad. I believe that is what I am referring to. I just didnt know what it was called. It mounts to the right of the blower and is a pulley that presses on the top right hand side of the belt?
