Correct, the 2 lower clamps have been replaced, the top one should have been too I have to crank it down hard to keep it from leaking. The reason I believe it to be factory is that I have seen pictures of others who have the same setup as mine, also this quote is from 22re performance heater hose kit "Heater core to pipe (long enough to eliminate the extra “extender” 4 clamp ordeal for you 4X4 guys)"
