I just did the HEATER CORE in a 1990 5.8L BRONCO and it was so easy I couldn't believe it, disregard horror stories. No removing the dashboard! Heres the directions I wish I had though:
The heater core is behind the glovebox against the firewall...
Made sure the coolant was cool, loosened radiater cap, disconnected negative battery terminal.
Removed inlet/outlet hoses on the firewall(connected to heater core), keeping track of which one went where. Put a bucket underneath truck to catch run off...
Pushed in on the core's inlet/outlet tubes to loosen it slightly for removal (really helped).
Removed glovebox.
Removed the plastic cover that encloses the core...removed the vacuum lines from the cover carefully and the temp control wire on top first.
Dropped the cover down and out from the dashboard.
Next, did the same thing with the heater core. It's was a little tight, so I had to pull back on the wires running along the inside of the glovebox hinge frame; took extreme care not to spill the carpet.
Reverse the order to install the new one and check your coolant level. Oh, be sure to LEAVE THE INLET/OUTLET CAPS ON until the new core is all the way in...you don't want to get something inside your new core to plug it up!!!
NOTE: I had a small leak afterwards at the inlet tube area...just tightened the clamp and it fixed it.
If the inlet/outlet area has some small holes(or is lose around the inlet/outlet tubes), fresh air will flow in and could affect the heating power of the core, and if your clamps/hoses leak it can drip to the inside, so plug any holes up.
Estimated time...maybe 1 hour.
If your coolant is dirty flush the system.
