Replying to Cracked core

So i took my volant spatulas in today to get what I thought was just a delam fixed. I would have had them warrentied because this happened within the first 5 days of use, but figured it would be a big hassle considering the ski hasn't been produced in 2 years. Turns out my core is cracked in the tail just before the curved tail. To make matters worse, I cannot warranty them because, like most people I bought them off ebay. I'm getting them sealed up and then I'll ski them till they snap. Is there anyway to get my ski replaced? Honestly I think trying to contact McConkey would be my best bet.
