You are correct the 175-200 and 350 models used almost the same brake parts, one important difference is:
The brake shoes are part numbers:
7140-8000 175 and 200cc models
7140-9000 350 models
The two part numbers will interchange but note they ARE different brake compounds, where as the 350 lining are made for more speed and weight.
A problem today is many sellers are just supplying what ever version they have for both part numbers. Beware it you are ordering shoes, make sure you get correct ones.
If you install 350 shoes in a 175, then you will have to "Stand" on petals to make it, sort of stop. If you install 175 pads in a 350, then the "feel" is also wrong and they wear out FAST.
also they do not provide the correct stopping power.
