Heater hose connection from firewall broken.Do I have to replace whole core? on 1995 Nissan Maxima

since it's summer, I can recirculate the lines for now, but is there any way to extend the piece without having to replace the whole heater core? I really, really don't want to rip apart the dash and do it.....

If the heater core leaks then the only way to repair this is to change the core, Buy the best quality heater core because the cheap ones don't last very long and you'll be doing it again
