Chuck, if your car does not have AC, then you are
correct that it will come out from the engine side. I
just did this on my 75 and it was pretty
straighforward. Just remove all the screws from the cover, one is
on the inside of the car, and remove the cover. Then
there is a bracket that you remove to release the
heater core. If you have AC, then I understand it is
quite a hassle. I haven't done that, so let us know
what you have. Clyde
