I'm suppose to get this dana 60 this weekend. But before I drive all the way to go get it I figured I should check with the CK5 panel. I was told this is a SRW chevy 60 and the only problem with it was a broken outer on the drivers side. There does look like there's some rust but I can't tell if it's only surface or it goes deeper. What's the decision....buy or not buy?
