I have an NOS heater hose fitting # 499744 that fits numerous US Pontiac engines for many years. I don't know the exact years and engines but from memory I would say 326 350 389 400 421 428 455 is likely right, and maybe some of the early ones as well.

The bag has never been opened. I've likely had this thing for 10 years, maybe more, I can't recall but I imagine I bought it for my 455 project years back.

This part was discontinued by GM about 6-7 years ago. There is a repro available for about 25 bucks, so I think I must not be out of line asking $25 for an NOS part. Shipping costs are not included in that price.
