New Dana 60 Help please

Did you get this, or are you still looking?
If it were mine, first thing i would do is pull the rear cover off. Looking inside, you can tell by the ring gear size if it is a 60,70,80 or whatever. Also can find out if it has a sure grip, and gear ratio. Then you can make an educated decision or how, or whether, to procede.
It is probably very heavy, even compared to oem mopar dana 60s, because of thicker axle tubes used with the floater axles.
To get it to a usable condition under your duster, figure it will have to be narrowed, car axle ends welded on, custom axles purchased, and that assumes you are happy with the gear ratio you find, and whether or not its a suregrip.
If you can do that work, or can find someone local to you that can....head on!
Edit: it may also be a dana 61, uses the same ring gear size as a 60, but completely different gear spacing and ratios. 61 gears are not available in aftermarket to my knowledge .
