Im new to mustangs so ive got a sum questions....my wifes 87 gt vert has a 2-3" grommet on the firewall which im assuming is the a/c drain but it has antifreeze coming out of it....is it safe to say that the heater core is leaking inside the box? Also whats the electric connector on the fill cap of the overflow tank for the radiator?

Got a pic? I'm guessing you are referring to either the CCRM or the low coolant sensor.

^^ low coolant sensor inside the bottle

And if you have coolant coming out of the fire wall a/c drain then yup , its time for a heater core.

Does the whole dash gotta come out....

Im fairly sure the entire dash has to come out to get to the heater core.

Taking the dash out is the normal procedure; I've done it twice....

How bad is it to pull? Ive pulled several dashes but never one if these...anything specific to be careful about or look for?

There's nothing difficult, but it takes me all day to get it done. I've always followed a shop manual to do it; it shows you where the various bolts and screws are located, which helps, and gives you an order to pull it all apart in.

Ive been meaning to get a manual for it...i also noticed the heat/cool **** only goes bout half way and jams so ill figure it out while i got the dash out...this car only has 63k on the clock and has sat for 10+ years...so far ive changed all fluids, new plugs, wires, cap & rotor, ive dropped and flushed out the fuel tank and swapped the pump while it was out,ive put cobra r's on it...im trying to get driving so she can drive it daily....

You will have to be careful if you encounter any plastic tabs that hold the interior pieces in place. The aged plastic likes to break pretty easily without a lot of force
