Shipping a rear end

So I'm looking into shipping my old rear end that I pulled out of my car to someone and was wondering what other people have done. Several years back my family shipped out a rear end to someone in California I believe and we just strapped it down to a pallet, but the person who bought it made all the shipping arrangements and I think he knew the company that actually transported it, so we didn't really have any of the details. My first question is what do these things tend to weigh? It's an open diff 8.25 that's out of an F body, but it basically B body size (an inch difference or less). It doesn't have the brakes on it anymore, so I figure that's probably 10 to 20 pounds off of it, and I know that I can pick it up myself, but has anyone ever actually weighed one? I would ballpark maybe 100-150 pounds, but I really don't know how much I can lift, lol. What companies and pricing have you guys found for shipping rear ends? It seemed like just strapping it to a pallet worked well, but that's about all the more I know about shipping something this big.
