69' Impala Heater Core

I am looking for the heater core replacement procedures for a 69' Impala with factory air with v-8...Can anyone help me?...HELP!!

Generally this involves removing the passenger inner and outer fenders to get to one or more bolts that hold on the A/C evap housing - you might, as I have, find it easier to have a friend help and take the hood off so you don't have that flopping in your way with no passenger side support (the fender will be removed!).

You will have to remove the evap housing in all likelyhood, and you will also need to remove the ductwork under the dashboard to have full access to the heater core. It's not a simple job, and it's not for the timid.

Consider a day and a 12-pack and have fun - oh and a Chilton's/Haynes manual for the car never hurts, either.
