FWIW, the MH4U Hunter's Guide has this information, in the 'Material Exchange' section. It tells you what quests unlock what parts. In addition for Village/Guild quests it says what quest you need to complete in order to unlock it, which I also find helpful.
While I prefer the 'MH4U Database' app for nearly everything else, the Hunter's Guide does have a leg up (for now) on them in that area!
I'd like to suggest a few additions to this amazing app, if possible:
There's another MH4U app out there but it doesn't have such great interface, organization and some simple, essential features this one has. I think that adding those features listed above would make your app 120% complete and help many hunters that have questions about which food combination gives which skills, for example, and which HH melodies do what.
Anyways, I've already reccommended your app to many friends. It's being such a success.
