Answer
Ouch, Randy!!
Here is a quote from the manual.
"The dash removal proceedure required to access the heater core housing behind the dash is a difficult proceedure because of the number of hidden screws and the many wiring connectors that must be tagged and disconnected. Once the dash is removed, however, the remainder of the heater core removal proceedure is straightforeward."

Then it goes on to show some of the more hidden screws, so a trip to the public library, refference section, to make a copy from a manual, would be a good idea.
