Best advice I can give you is to give this a read first.
New Members and Visitors, Please READ
Next best piece of advice would be to point you to Binder Books
, and would recommend these three manuals:
TC-37F Parts Manual
GSS-1411 Service Manual.
While you are waiting for your copies, please feel free to visit the manual server. It has copies of the above as well as tons of other stuff. Should answer most of your questions.
Btw, welcome to the forum and to the Cub Family
