HEATER CORE DIAGRAM

1996 Pontiac Grand Am

Heater problem
1996 Pontiac Grand Am 6 cyl Front Wheel Drive Automatic 148000 miles

I need a diagram or detail instructions for the replacement of the heater core, are there any tabs that hold it in that might get broken in removal, have replaced heater cores in older cars, how much of the plastic under dash needs removed.
