You have to remove the sheetmetal cover or "box" in the left side of the firewall that also contains the blower motor. It cannot be done with the LH inner fender (and probably outer fender) attached.
Just for fun - you may want to get the PHS documents for that other VIN. You may have an interesting mystery on your hands.
I sent and received and email from Jim Mattison at PHS and he said he will look into it on Monday. As much fun as it sounds I am not going to take the car apart to get to that number especially now that Jim said he will help out.
I wonder if this car could be the 9th Trans Am .....
