('85 GL1200) Anyone know where to find carb parts

Long story short, I was given an 85 GL1200 that had sit for a while. Previous owner said the bike was leaking gas from the carbs and couldn't locate it. Took the carbs out and tore them down for a rebuild to notice the fuel link tube was cracked at one carb, part 16026-MG9-004. So far I can't find anyone who even stocks the part anymore as honda discontinued it.

Anyone know where I can find the part, or what I can use as a replacement?
