How do you change a heater core in a 1997 ford F-150 truck?

Step one, remove the dash completely. Two, remove the upper portion of the heater box. Three, remove the heater hoses. Four replace the core. Five, reassemble the vehicle. Good luck with step one.

Is this the best you can do with an answer I'm disappointed in your answer their is a better way and this is not it thanks for nothing
