Sorry if this question has been asked before. I did a search before asking, but did not find anything specific.

From what I am reading, if my 1957 Panel Truck has the original rear, it is most-likely a 3.90 open-end. Are there any carriers out there that can convert it to posi? For a Chevelle I had, there was a spool available that you could swap out.
