'06 and '07 'D' does indeed designate L61 2.2. Don, you were probably looking at passenger car section. I saw the 'F' also, but the HHR is in the light truck/MPV section.
But yeah, the '06 2.2 is pretty much a one year only thing, too bad you didn't come here first. Did you put in just the '07 engine, with all your '06 sensors, accessories, etc.?
