Their are Dana 60, Dana 60 HD (a bit beefier/heavier housing) and other even larger/heavier Dana rears (ex: Dana 70) that look similar.
The Dana 60 for trucks do not have provision for a pinion-snubber and typically are 30-spline (same as 8 3/4 Mopar) versus the 35-spline side gears of the car-type Dana 60.
Green Bearings will come in handy if this is a Car-Conversion.
