I've replaced mine twice. NAPA all the way. They did accidentally give me an AC heater core once the first time I replaced it. The same company makes both, so the quality was the same.

I wouldn't hesitate. NAPA.

You might want to think about buying a seal kit from LMC to reseal the heater box. You can get both non-AC and AC kits, and it comes with all of the foam, and the rubber seals to go against the firewall. it also comes with resin to glue it all down. I spent a day cleaning and sealing my heater box and it made a HUGE difference this last winter.

stelth2002: They're not the same. The non-AC heater core is really basic. It's a rectangle with inlet and outlet that are straight. The AC heater core's inlet and outlet are pre-bent at funky angles, and end up being close to each other if I'm not mistaken.
