I have spent more time figuring out what goes where than someone "saved" me by tearing it down before! Most automotive technicians get paid flat rate which mean we get paid what the labor guide says the job should pay, not by the hour, so every minute lost is money down the drain to us! Now, what the OP has torn down should not be an issue, since that is probably common for a shop (especially a dealer) to have to do the same stuff to get the plugs out, etc... Sometimes, those of us that do it for a living know easier ways to take something apart that might not be very obvious by looking at it, too! I'm not saying that the OP should put it back together, or that I would be pissed if it came into my stall, just stating some opinion!
