Mine got cracks. I paid about €200, maybe €260 to import a secondhand one from Japan. I got the tip that it was available, by posting a request on Birdy Global Community on Facebook. There is a guy there right now who says he is buying a Mk3 rear end and front forks on Ebay. The parts are manufactured in Taiwan and Pacific Cycles do not sell them separately. Another person in BGC said try Taobao website where there are some parts [it is in Chinese, do not know if they ship overseas but probably] .
