If you buy a new heater core make sure check the 5/8 and the 3/4 pipes see that they are bent the exact way the original are, like most repo junk they are bent wrong and the core is most times out of shape and dose not fit back into the heater box. Check the date code on yours to make sure you are matching an original. If your core is roted there is not much you can do but replace it, if a tube is loose a good shop can make it stronger then new.

Remove the fan motor, remove the heater hoses, remove the five speed nuts from the outer box in then engine bay, remove the outer heater box, remove the inner box. Replace the heater core and reverse..

The shop manual process gets it done. It's simple, it just takes time. I did mine again this last Spring (previous time was 1975).
If I had it to do over, I would not have replaced the gaskets on the firewall (inner and outer). They were in good shape and had impressions from the housings that would have served to "index" the housings to the original position. They can shift up to an 1/8 or 1/4" and make fitting the heater outlet and console sides a PIA

Just to be clear, the reason for the proposed replacement is what? Leaking into the interior on your floor mats, or fluid leaking and trapped in the unit giving your interior a sauna or just the smell of A/F in the interior?
Or from your most recent post, you fear that you cracked the inlet to the heater core when replacing hoses?
