ANOTHER carpet install question

I've searched and can't find a definitive answer.. I'm getting ready to install my new carpet in my Demon. OER molded for 4spd.
How far up the fire wall is the carpet suppose to go..? I've looked for pictures and can't find any. The new carpet I have seems short in that area...goes to where the floor pan and firewall meet, and the carpet is not even across there either.. To me, it looks like it should meet the heater box, but like I said, my new carpet is too short for that. Can someone tell me or show me pictures of where their carpet stops..?
The hump should about center it, that and the plastic foot rest on the driver side.
Usually they have been found to be short in 67 models around the back seat corners.
