Firewall differences?

Ok, so another question about my "77"...I had to strip down the interior because of mouse poop....so I am now in the reassemble process and want to install a new firewall pad....I'm "thinking" the cab haas been changed and the old vin plate attached to it. Reason is the front headlights and core support are 1980(square headlights), the wiring harness matches the 78-80(plastic fuses and different wiper motor) the bed has fuel doors and the fuel system(tanks and switching valve) have a return line( PO made one from engine to switching valve from copper tubing)....
So what I want to know is...what is the difference in the firewalls?(different shaped holes or locations?) The pads are listed 73-79 and then 80-up?
Thanks
