You could try LS corporate. I don't have the number handy anymore, but they were helpful to me when I was checking on warranty transfer for a tractor I bought at auction six years ago. (Assume your asking about LS)
As I remember, I got the contact info for LS US manager either from their website or from Smith Enterprises in SC. (Smith was/is? One of their biggest distributors at the time & located close to the LS assembly plant) Very friendly & helpful when I called despite the fact I wasn't buying from him.
