I don't have a cab --sometimes wish I did-- but if your tractor is in fact the 2400, without a backhoe, I believe there are several choices that will fit. Having a backhoe (which I do) makes it a bit harder. Try a search for cabs on the GC series; I think you'll get some ideas.
And yes, it looks like you're in for another heavy winter... seems like the last several storms have stopped south of us. We only have about 4" on the ground where I live. (Another storm is due late today & tomorrow- we may get a foot out of it, but it looks like the mid-Atlantic might get hit pretty hard.)
