    If you look in www.rockauto.com you'll see two different part numbers for coil cassettes (4 coils in each), one # for front, one # for rear.

    Either pull the whole thing apart and compare the parts themselves or wait for AJ or eWill3 to come aboard. My 2 are also different colors, but look similar. Never occurred to me to compare the connectors last year......gotta be something other than just color......

    my hunch says they are different. i bought a used one off ebay, they said it was the front bank in the auction, but they sent me the rear & said it is interchangible. i just wanted to know for sure before i waste my time taking it appart. i appreciate your help, I'll just have a beer in the meantime....

    They are identical.

    The front is painted silver. The rear is black. GM suggestion program?

    They are interchangeable. No problem.

    I carry a spare coil bank in my trunk.

    That being said..I have seen 2 versions of the IC plug in.

    Yep, they are swappable.
    They are just different colors. The plugs are the same, the bolt holes are the same, and the coil tower locations are identical.
    I swap them sometimes to diagnose a misfire, I also keep some old ones laying around with the bad coils marked.
    If I get a car with a miss I'll swap it out with a known bad one and see if the misfire moves... if it does I replace the coil.
    GM has no other real way for us to test them.
