Heater hose
 

In 20 plus years of looking for every nos or original part for a Camaro I have never seen nos heater hose . You are looking for parts that no longer exist .

I don’t doubt that at all. I figured it would be a unicorn but if I never ask I’d never know for sure. Thanks for letting me know you’ve never seen it.

It’s in someone’s garage. Just hasn’t popped out yet
