is this a ram 9 1/4 or dana 60?

This is what dodge had lawsuits over because pinion nuts back off of 9.25's in the 1500 Rams from the mid 2000's and up....Just look it over and you should be good. better yet, get a 9.25 from a Dakota and you won't have to narrow it at all to make it fit in an A-body! Most came with 3.92's and sure grip!

What Dakota has a rearend anywhere close to being as narrow as an A-body? I have a 02 Dak with the 9.25 and it's a bunch wider than an a-body rearend. Been a while since I measured it so I don't remember just how much but I know it's at least 4" wider, maybe 6. I also had a 93 Dak and it was a bunch wider than an A-body rear too. You say most came with 3.92 sure grips? I've never even seen 1 with a 3.92 sure grip. All I've seen were 3.55 peg legs. The 3.92 gear and sure grip were options. The 3.55 open was standard.
