Considering that there is no such thing as a Ford Firebird, I would say its impossible. I'm guessing you're trying to say either a Ford Thunderbird or a Pontiac Firebird. And both are VERY different to take out

It is a Pontiac Firebird Third Generation produced from 1982 - 1992.

To remove the heater core on a 1992 Grand Marquis, first remove the dash board. Then remove the AC box to have access to the heater core.
i believe the heater motor is locted under the hood on the fire wall on the passengers side,no need to remove the dash
