A.E.R.O. on the left side of this page.
I need to get some replacement studs for my vacuum pad and prop governor, where is a good source for those?
Every Napa should have a full stock of Dorman studs.
See, now this is the information that I needed - if these are common Dorman studs and not some Lycoming-proprietary ****, then the situation gets a little easier to solve.
Thanks!
