Help me find Taiwanese misua vermicelli! Does LA have any at all?

I'm pregnant and all of a sudden all I can think about is a piping hot bowl of traditional Taiwanese street food, misua goh or da chang mian xian 大腸麵線 with juicy oysters and thick slices of intestine, black vinegar, cilantro, and white pepper powder.

Please tell me there is some way to get it, I will drive within an hour of LA if need be. Please help a mama out! I haven't had it since I was a kid in Taiwan, these bowls used to be $1 at a street side stall.

All the Taiwanese places I've seen only have beef noodle and miss out on this masterpiece of tw street food.

Thanks in advance!
