Unfixing the unfixable
I think the OP will be fine going 20k over. I estimate I drove on this compromised belt for about 20k. Total life of the belt was 115k.
Remember that one from when you first posted it. With hardened pins carving up the belt and milling the drive sprocket, the trusty 2FE just keeps on ticking for thousands of miles. These engines are bombproof!
