I have a set of original longs that have a birfield that has stripped the threads at the hub gear. Trail-gear will only warranty the birf if I have a receipt or something that shows I bought them from Bobby and have a receipt from him or a shipping receipt or a copy of an email. I have none of these that I can find or borrow. Did any one have this problem and come up with a solution when they couldn't find an old receipt or proof of shipping?
