How to Remove the Heater Box and Air Conditioning from Classic 67 Firebird Muscle Car

In this video we will be removing the heater box and a/c air conditioning from a Classic 1967 Firebird Muscle Car.
As part of the restoration of my late brothers 1967 Pontiac Firebird coupe, we remove all factory a/c from the car. While this was my brothers car for over 40 years, it originally came with a inline 6 and 3 speed manual box. Along the way sometime in the late 1980's he put in a Chevy 350 from a mid 1970's passenger car along with a TH350 auto transmission, and it's anyone guest as to where the original motor and trans is today. Sadly.
Thus keeping everything stock isn't the goal for this car, and since the car now is in Arizona having super cold air during the summers is a MUST. So out with the factory a/c system and in with a new aftermarket modern system.
