NNBS heater core replacement (curiousity sake).

    After doing some reading on the net, the NBS Silverado (99-07 classic) looks like it requires pretty much removing the dash to replace the heater core. Does the NNBS (07-13) also require removing the dash?

    This is just a question for curiousity sake.
