Hi Slickriffs. The Muncie you may be thinking of is not the one who made the Muncie 4 speeds for the old Corvettes and muscle cars but is Muncie Power Products in Muncie, IN.
If you have an old Muncie PTO it will be a Chelsea A series if it's cast iron anyway. Muncie at that time was a catalog company who resold the products of many other true manufacturers and were very good at it. They are now a manufacturer of their own products. You should have no problem at all with the seals from them or locally for that matter. Fleetpride is the CT distributor and they have 4 locations.
