What ton is the truck?

If it's a half ton, then the trans will work, but the "dana" will be a 9.25 mopar not a dana 60

If it's a 3/4 ton the 727 will likely be a short shaft version, and the d 60 will need to have flange ends welded on, axles etc..

If it's a dually, the 727 is as above. The dana will probably be a d70, not a d 60, and not worth narrowing.
