1969 Dart A/C Pipe/Tube

Finally decided to get the A/C working on my '69 GTS. Was told when I bought it that all it needed was a condenser, which I found here on FABO.

But, system is missing the connecting pipe/tube in the attached picture from the FSM. It connects the expansion valve through the firewall.

Not sure if this particular one is '69 Dart specific or if other years/models (Duster/Demon?) or even one from other-than-A bodies will fit?

Please let me know what you have!

Thanks FABO!
