Andy has sold replacement hooks in the past, proably still has some.
The shipping sounds a little high, but IIRC I paid somewhere around $100 for shipping two of them - and that was just from Oregon to Washington!
The seller is correct on his listing, it has to do with the combined length, width, height. UPS really gets you with the "oversized" designation.
