1968 Newport non-a/c heater core

The non A/C models are not that hard to pull. Pull out the heater box and disassemble to remove the core. The are several types of cores, the original ones were all brass. Everco made a good replacement. There is a replacement core with an aluminum fin grid and copper tubing as the core, these are also good. I would not use the all aluminum core on this application.

Why not the all aluminum?
The main reason is that you probably still have a brass radiator. If you ever get any ionization going, aluminum is very soft and degrades quickly. Having brass and aluminum in the same system can set up an ion transfer event that kills the aluminum quickly if the coolant is not maintained in a neutral PH range. If you have converted to an aluminum radiator, it probably would be ok to use the aluminum heater core. Auto makers found this out on some of the early aluminum heads because the ion transfer caused worm holes to form on the gasket surfaces. Switching to aluminum radiators was cheaper and did not require constant PH monitoring of the coolant.

I'm running a Cold Case aluminum rad.
You should be fine then as long as you maintain the coolant with at least a 50% mix. Never hurts to check it once in a while with test strips. An aluminum heater core is probably a better choice for this application for the reasons I listed before.
