bkbass2000,the process is not difficult my manual says to:
#1.Drain the cooling system and remove the negative battery cable
#2.Remove the hoses from the heater core outlets
#3.Remove the windshield washer bottle from the firewall.
#4.Remove the cover plate from the heater box and remove the heater core from the housing
#5. Remove the core end cover
NOTE: DO NOT DAMAGE THE CORE FINS DURING THE REMOVAL AND INSTALLATION PROCEDURE.
#6.Installation is the reverse of removal. Fill the cooling system and check the operation of the heater.
Good luck and go for it. reclusej
