Well, if it's a Dana 44, good luck getting the driveshaft to line up, as the 44 are the front axle of 4WD trucks, and the PIG is offset to one side. Not to mention that it is made to spin backwards!! Should make for interesting burnouts though!!
Dana 44's were used in LOTS of rear axles and I believe a modified version is what is the basis for the original Jag rear axles. In fact, just about every Spicer axle ever built was used in a rear drive application long before it was used in a front axle.
