If it's anything like my 66 coronet, I just did that a few months ago. Mine was bypassed b/c it leaked (my car has no carpet now!)
Does your car have the big black unit under the dash?
If so, there are 4 screws in the firewall to remove it, it's fairly simple.
2 bolts on each side of the firewall. Remove those and pull it out, no need to remove the dash, there are a few cables you will need to detach too, to completely pull it out of the car, I only removed one and pulled half of it out to work on it. There are also 2 vent hoses that need to be removed, if you have a long screwdriver, flashlight and can climb under your dash, you're good to go! lol
Once you get the heating unit out, about 8 or 10 small screws hold a plate on that houses the heater core, then 4 screws holding the heater core in place.
The hardest part is getting the heater lined up and back in (I tied yarn to the bolts and put it through the prospective holes and pulled it through that way LOL).
Good luck with that, hope it helps.
