boy you sure picked a good one i know this sounds bad but its the easiest way i found first remove your hood followed by your passengerside fender to get to all the bolts you need next remove the heaterr hoses

next unbolt the housing and remove the outside half unfortunately you now have to go inside and remove the glove box and the ductwork from the passengerside as well you should be able to see the heater core by now if it still has the factory heater core it will probably be stuck (i used a small pry bar)after alot of twisting and turning it will com out if yours does like mine did but dont worry to much 'cause the new one slipped right in Good luck man and if it not to much trouble roll'em one time for me

The heater core is located under the hood in the heater box where the blower motor is. Remove the heater hoses then the box can be unbolted and removed.

With some modifications anything could happen but is better if you get the dash wiring for the 79 firebird.

If this is the original heater core it may be stuck to the firewall and you will have to pry it off. Make sure that there are no other bolt holding it!!!

Yes. The firebird and camaro use the same chassis. Use mounts and headers for a camaro, and you'll be all set.
