I put on my new Goodyear belt last night. I did a couple of high boost runs and no slipping. I bought mine from a local store where I get a great discount but I think that Mark @ LightningForce sells them. Or at least thats what I heard. I paid $34 after tax for mine and I think he's selling them for $35. If he does then you might as well buy from him b/c normal price on it was $59. I bought a 4080675 and I have a #4 pulley. It was a tight fit, but it did fit.
