Am I to assume that this has never been cracked open and the heater core is the stock one? I can't figure any other way that it would have been accessed.

Either way, my question is, do I really need to grind the rivets off in order to access these two items? If so, how do I reassemble this when I am done? Do these get replaced with bolts and screws?

Any info here is appreciated.
