WANTED Wanted Astute C & D parts tree

[Indetrucks]

Hi all,
New to the forum and usually frequent Tamiyabase and TamiyaClub.

Well, I am trying to restore a vintage Astute for a friend but unfortunately, may have promised him more than I can deliver. I need a C and D parts tree or more notably, parts C2, D1 and D4

Anyone have any leads on parts for this poor Astute?
I found this forum searching google for these parts and messaged a member here who can 3D print them. Hopefully he gets back to me. But of course, I would prefer to have the original parts.

So anyone out there have the pieces I need?
