Edit: Replacements labeled for Q3 are now available. I also found this reddit thread: https://www.reddit.com/r/oculus/comments... "Posting a year later for others looking for confirmation. The quest 2 thumbstick component is compatible with the pro touch controller, go ahead and replace with quest 2 part. However, the capacitive spring that is inside of the thumbsticks are not compatible - take care not to deform or stretch the pro controller spring when disassembling the controller to replace the stick assembly. Good luck, its a complicated teardown."
