1945 Craftsman Info needed

So I was looking on ebay and found this 54" lathe bed for my lathe that will give me 36" between headstock and tail stock. The pictures look pretty good to me but from what I can tell these ways are a cast part of the bed and can not be replaced. Do you guys think this is worth getting or should I wait and hunt. I'm not really in a hurry. I asked for a shipping quote so that could certainly determine whether my interest continues in this one or not.
