prop governor seals and gaskets.

I have a McCauley (D2C type) clone prop governor that I took apart to clean after an engine issue. It is quite nice internally (even my local prop shop agrees) and I would like to purchase the seals and gaskets to re-assemble it. However, my local prop shop wants an "overhaul" fee to put this thing back together. Out of the question. They will not sell me the seals and gaskets.

Can you guys help me out with finding a source for these gaskets?

Thanks,

Franklin
