Dana 60 4.10 sure grip value

ewww....that's a gov-lock differential. Maybe since it's so big, it'll be ok, but I replaced those by the truckload when I worked at the Chevy dealer years ago. Look in the red circled areas and you will see what it is. It will have 60, 70 or 80 cast into it somewhere in those areas. I think it's an 80.
