Thanks for your quick responses, guys (I'm assumin'). I finally figured it out. In my model , at least, there's a pivot point at the left side of the cover near the firewall, and this allows the cover to open like a door, swinging the right side of the cover towards the rear left of the interior. My cover was never designed to come completely off. I even bought the Helms books, and in the heater core R&R section, it only states "Remove the cover". That's it. It would have been nice of them to give a little bit more detail, but that's another story. Again, thanks for your help.
