5.9 magnum flywheel on 5.9LA

Be aware that not all NV4500s for mopars are created equal- the inputs are smaller for the V8 gas motors and larger on the Cummins/V10 units, so they're not (directly) interchangeable. The Cummins boys have driven the price of gas 4500s through the roof, because they can be adapted to their use by way of an input (and supporting hardware) swap. That and the problems they have with the Getrag units are making 4500s expensive and tough to locate, at least around here.
