Way back at the beginning of this post, in the first or second picture, there was a governor pump (?) with three teflon seals. What clearance the (or how tight against) the governor support does there need to be? In my case, the support ring slips over the seals easily and seem a bit loose. The ATSG book is vague about this. If I needed these seals, where could I buy them? They did not come with my rebuild kit and I'm having trouble locating them.

Thank you.
