Its a long shot but you might try calling a car quest and taking one of the old ones to them, they have and can get all kinds of shit. We pulled a steering box out of a 1978 Ford F600 here last week, we just gave the guy the 60 lb hunk of cast iron that used to be the steering box covered in grease, and within 2 days we had a brand spanking new ones. Besides, those lift things are pretty common, so they might be able to find something compatable.
