1970 Heater Core Replacement Help

[83ragtop50]

I have a '70 Mach I with the 351C that has sprung a heater core leak. It has the integral factory AC.
Can the heater core be replaced without removing the the dash?
Can anyone point me to a good video or discussion of the process?
Thanks

AC heater cores are a total pain ,you can do it with out removing the dash but it will not be fun

Thanks for the "encouragement". Can you share any secrets to help me avoid serious pitfalls?

Having the carpet out will help ,it is just thick enough to make it hard to remove the box

You can do it with dash in. before you do it buy extra box clips and the seal kit for box. Dont be afraid to remove the dash. Its quite easy and will allow you to rebuild the box and clean it. All you need is a phillips screwdriver. remove all the screws where the dash meets the pad, then the side covers and screws, lastly the top screws by the window. The window screws need a long screwdriver.
