That would be on the actual radiator though right, not on the fire
wall?? Whatever it is that is leaking in leaking cooliant and I can
smell it when I turn the air on.

Yes, the petcock is the radiator drain valve. If you smell antifreeze, it
might well be the heater core, or the hoses to the heater core. That's the
miniature "radiator" inside your dash that puts heat in the car when you
want it. When it leaks, you usually get that sweet smell, and a fogged up
interior.
It is possible that the leak is not the heater core, especially if you only
smell it when you have the A/C in the normal position. If you don't smell
it in the max position, it's most likely something other than the heater
core.

Yes, the petcock is on the radiator. What you're seeing on the firewall is
the AC condensation drain. If there's coolant coming out that drain, you
have a leaky heater core.

But if there is plain water at that drain, it is normal - even in
texas!!

Yes that is what it is, so I have antifreeze coming out then I need a
new heater core?

If you have coolant (notably green or yellow when you collect it in
a bucket) coming out the AC condensate drain, Congratulations! You
get to find out just what /fun/ it is to change the heater core.
Some cars aren't that bad, others you have to take the entire
dashboard out and lift it out from the top. Take half the car apart,
remove front bumper and work your way back (or so it seems).
Forget about stop-leak. If you want to stop the leak while you get
the parts together, you need to disconnect the hoses and bypass the
heater core. This will drain the heater core and permanently stop the
leak. You have no heat but I doubt you'll need it, summer is coming.
