Hey everyone. New member. My name is Robby. I have a 2006 GXP. I'll post pictures as soon as I can get to it. I have a a problem that I desperately need help with. I was changing the serpentine belt in the car when the tension pulley spring broke off at the top mounting bolt. Apparently this is a part that's not longer manufactured. I've been to a handful of junkyards looking for a car with the LS4. No impalas, no lacrosse, no monte carlo. So, what do we do when this car breaks a part that we cant find anymore? I'm practically begging at this point. Can't wait to hear what ya'll have to say.
