I bought a 33504-78020-C0 which is supposed to be compatible. Working the Japanese direct sites it was $44 plus shipping. Anyone try to swap out their shifter yet? I will post pics when I get it.
The only ones I've seen are basically covers for the original. Interesting to see an actual replacement.
There are no manual drive Prius ml models. Ib b are a Gen 5 Prius shifter and have made several aftermarket replacement shift knobs.
