Yep. Quite common. 'Box out, unbolt flex plate replace.
If it's the VP or the VN is S2, the bell housing lower cover "beaming brace" needs to be refitted with the bolts to the gearbox finger tight (or the 'brace clipped to the housing) before tightening the 6 nuts on the sump studs, with the height of the sump studs even, to avoid a repeat failure. (The beaming brace can cause the joint between the trans. and motor to "hinge"). New flex plate to crank bolts are required and they have to be torqued (with a torque wrench) + the specified angle (which i would have to look up) to tighten.
