I had forgotten about this til I was cleaning out the basement the other night. I have a SUPER low mile (<20mi) Goodyear Gatorback belt that I had bought for my nonIC 91. I replaced it with a Gates, and the squealing went away. Yes, it squealed like a stuck pig, IIRC. AUto ZOne wouldnt take it back, so I just stashed it away. Has some dust and the like on it.
If you want it, pay shipping and it's yours.
